    A theoretical analysis of the functions values fulfill is described by focusing on two widely accepted value

    functions: values guide actions and express needs. The interplay between these two functions yields a

    three-by-two framework differentiating values according to their pursued goals (personal, central or

    social goals) or their expressed needs (survival or thriving needs). The three-by-two framework results

    in six subfunctions or basic values (structure hypothesis) assessed with specific marker values forming

    the Basic Values Survey (content hypothesis). The present paper tests these theoretical hypotheses in a

    large national sample of Brazilian physicians (N  = 13,414). The results support both hypotheses and pro-

    vide further empirical evidence for the functional theory of values. Discussion centers on the theory as a

    refinement of existing value models due to its parsimonious and theoretically-driven approach, and its

    merit as an additional theoretical tool for understanding the structure of the value domain.

    1. Introduction

    Schwartz’s theory of values is an important legacy in social

    psychology that provides conceptual, methodological, and empiri-

    cal contributions to map a set of universal values (Maio, 2010;

    Schwartz, 2011). Throughout the years the theory has promoted

    multiple configurations of the value domain, including seven (Sch-

    wartz & Bilsky, 1987), ten (Schwartz, 1992), eleven (Schwartz,

    1994) or nineteen (Schwartz et al., 2012) motivational value types.

    As a result of these multiple (and somewhat conflicting) configura-

    tions, some researchers have tried to identify a congruent pool of 

    dimensions, suggesting between six and eight motivational types

    (Hinz, Brähler, Schmidt, & Albani, 2005; Perrinjaquet, Furrer, Mar-

    guerat, Usunier, & Cestre, 2007), whereas others have preferred to

    consider only the two bipolar higher-order dimensions of self-tran-

    scendence/self-enhancement and conservation/openness (e.g.,

    Caprara, Alessandri, & Eisenberg, 2012; Strack & Dobewall, 2012).

    We believe these multiple configurations lack parsimony and

    theoretical focus, and might also hinder scientific advancement

    when studies are to be compared or meta-analyzed. In the present

    article we discuss a parsimonious and theory-driven approach

    explaining the functions values fulfill that canbe useful in integrat-

    ing previous theoretical value models. In particular, the theory

    integrates models that conceptualize values as guiding actionsand expressing needs. We start by describing the functional theory

    of human values (Gouveia, 1998, 2003, 2013), and then report a

    study gathering empirical evidence for its appropriateness in a

    large national sample of Brazilian physicians by testing two spe-

    cific theoretical hypotheses.

    2. Primary functions of values

    The functional approach is popular in attitude research (Maio &

    Olson, 2000), but research examining the functions that values ful-

    fill has received less attention (Gouveia, 2013). Nevertheless, two

    primary functions of values can be identified in the psychological

    literature: values guide actions (Rokeach, 1973; Schwartz, 1992)

    and are cognitive expressions of needs (Inglehart, 1977; Maslow,

    1954). The recognition of these two value functions has led to

    the development of the functional theory of human values (Gou-

    veia, 1998, 2003, 2013;   Gouveia, Milfont, & Fischer, submitted),

    which attempts to explain the underlying characteristics of the

    value domain structure.

    The parsimonious selection of these value functions is in line

    with research showing that the general structure of motivational

    systems is consistently subsumed by a two-dimensional structure

    (Fontaine, Poortinga, Delbeke, & Schwartz, 2008; Grouzet et al.,

    2005; Ronen, 1994). However, a theoretical and explicit explana-

    tion of the underlying functional characteristics of this structure

    has not been explored by the extant literature.

    The theory posits that the two value functions form distinct

    functional dimensions. The first dimension outlines ‘circle of goals’

    based on the type of orientation values serve when guiding human

    behaviors (personal, central or social goals). The second dimension

    outlines ‘level of needs’ based on the type of motivator values serve

    when cognitively representing human needs (survival or thriving

    needs). These value functions most likely arise from evolutionary

    conditions associated with human development.

    In order to survive in a hostile environment, humans need to:

    (a) establish bonds with others, while being able to make personal

    decisions for one’s own survival, (b) resist threatening group

    demands, and (c) make sense of the multiple meanings present

    in social interactions (Baumeister, 2005; Tooby & Cosmides,

    1990). This demand to simultaneously act autonomously and bond

    with a larger group leads to a functional and integrated set of val-

    ues that guide actions. The second functional dimension underlies

    the expression of needs that would threaten the survival of the

    individual, the immediate social group, and the species if not ful-

    filled, such as basic biological and social needs (e.g., food, self-con-

    trol) as well as needs that become more important once the basic

    needs are addressed (Baumeister, 2005; Maslow, 1954; Welzel,

    Inglehart, & Klingemann, 2003).

     2.1. Guiding actions

    Personal and social values are the two terminal value types iden-tified by   Rokeach (1973). Individuals guided by personal values

    (e.g., an exciting life, inner harmony) are self-centered or intraper-

    sonal in focus, while those guided by social values (e.g., true friend-

    ship, a world of peace) are society-centered or interpersonal in

    focus. Personal and social values lead individuals to emphasize

    respectively themselves or the group as the principal unit of 

    survival (Schwartz, 1992). Empirical studies have also identified

    values that are neither completely social nor personal, such as

    personal stability, health, knowledge and maturity (Mueller &

    Wornhoff, 1990). Although some scholars refer to this set of valuesas representing mixed interests (e.g., Schwartz’s universalism and

    security value types) and in opposition to other values (e.g., Sch-

    wartz’s stimulation value type), a different perspective is taken

    here.

    According to the functional theory, values that are neither

    exclusively personal nor social are located almost exactly between

    personal and social values because they are not restricted to the

    dichotomy of self-centered or society-centered interests. This set

    of values is thus congruent (and not in opposition) with both

    personal and social goals. The theory further posits that this set

    of values is the  central   reference source for the other values inthe sense that they express general purposes of life corresponding

    to basic needs (e.g., survival) and more general needs (e.g., self-

    actualization). Therefore, the first functional dimension differenti-

    ates values according to the orientation of their pursued goals

    (type of orientation: personal, central or social goals).

     2.2. Expressing needs

    Although the correspondence between values and needs is pro-

    posed (Maslow, 1954; Rokeach, 1973), there is little empirical re-

    search on values as based on needs (Calogero, Bardi, & Sutton,

    2009). Nevertheless, the literature suggests that all values can be

    classified as  materialistic   ( pragmatic ) or  humanitarian   (idealistic )based on the needs they express (Braithwaite, Makkai, & Pittelkow,

    1996; Inglehart, 1977). Materialistic/pragmatic values express ba-

    sic biological and social needs such as food and control acquisition,

    ensuring the survival of the individual, the immediate social group

    and the species. Humanitarian/idealistic values express needs that

    become more salient when the basic needs have been addressed

    (Inglehart, 1977; Maslow, 1954), including needs for information,

    self-esteem and intellectual and emotional stimulation (Baumei-ster, 2005).

    Materialistic values imply an orientation toward specific practi-

    cal goals and normative rules. Individuals guided by materialistic

    values tend to think in more biological terms of survival, empha-

    sizing their own existence and the conditions to secure it. Human-

    itarian values, in contrast, are based on more abstract principles

    and ideas. Emphasizing humanitarian values is associated with

    creativity and open-mindedness, suggesting less dependence on

    material goods. Compared with materialistic values, humanitarian

    values are not necessarily directed toward concrete goals, and are

    generally non-specific (Braithwaite et al., 1996; Inglehart, 1977).

    Materialistic values express survival needs while humanitarian

    values express thriving needs. The second functional dimension

    thus differentiates values according to their expressed needs (typeof motivator: survival or thriving needs).

    3. Content and structure of the value functions

    The functional dimensions can be mapped on a three-by-two

    framework, with three broad pursued goals (personal, central or

    social goals) and two broad expressed needs (survival or thriving

    needs). The interplay between goals and needs yields six specific

    subfunctions or basic values.   Figure 1 presents the three-by-two

    framework, indicating the specific marker values used to represent

    each of the six basic values further described below.

     3.1. Existence values

    The most basic physiological needs and the need for security are

    cognitively represented by existence values (Maslow, 1954; Ronen,

    1994). These values are compatible with personal and social goals

    within the expression of survival needs because the principal

    purpose of existence values is to assure the basic conditions for

    individual biological and psychological survival. As such, existence

    values are the source of reference for promotion and normative

    values.

     3.2. Promotion values

    These values express survival needs and focus on personal

    goals. Promotion values stem from a personal and materialistic ori-

    entation and are essential for securing self-esteem (Maslow, 1954;

    Ronen, 1994). Although driving personal and material accomplish-

    ments, such values are also important for successful social interac-

    tions and institutional functioning (Schwartz, 1992). Individuals

    guided by promotion values view hierarchy as an important

    demonstration of personal competence. Such individuals also cher-

    ish their own personal benefits and are practical decision-makers.

     3.3. Normative values

    These values also express survival needs, but have a focus on so-

    cial goals. Normative values cognitively represent the need for

    security and control as well as the pre-conditions for the satisfac-

    tionof basic needs (Korman, 1974; Maslow, 1954; institutional and

    social demands according to  Schwartz, 1992). These values focus

    on social rules with a materialistic guiding principle, reflecting

    the importance of preserving one’s culture and conventional

    norms. Endorsing these values also implies a vertical orientation

    (Gouveia, Albuquerque, Clemente, & Espinosa, 2002), wherebyobedience to authority is important.

     3.4. Suprapersonal values

    Like existence values suprapersonal values also focus on central

    goals, but express thriving needs. Suprapersonal values represent

    the higher-order needs of aesthetics, cognition and self-actualiza-

    tion (Maslow, 1954; Ronen, 1994), emphasizing more abstract

    ideas over absolute or material goals (Inglehart, 1977) and leading

    to a better understanding and mastery of the physical and social

    realms (Baumeister, 2005). Suprapersonal values are the source

    of reference for excitement and interactive values.

     3.5. Excitement values

    These values represent thriving needs with a focus on personal

    goals. The physiological need for gratification, variety and pleasure

    (i.e., hedonism; Maslow, 1954; Ronen, 1994) is cognitively repre-

    sented by excitement values. These values express a more personal

    orientation and non-conformity, contributing to a promotion of 

    change and innovation (Gouveia, 2013). Individuals guided by such

    values tend not to be orientated toward material goals in the long

    run (Guerra, Gouveia, Sousa, Lima, & Freires, 2012).

     3.6. Interactive values

    These values also represent thriving needs, but have a focus on

    social goals. Interactive values are essential in regulating, estab-lishing and maintaining one’s interpersonal relationships. The

    common fates and affective experiences of individuals are stressed

    by these values, representing the needs of belonging, love and

    affiliation (Korman, 1974; Maslow, 1954). Individuals guided by

    interactive values view social contact as a goal in itself.

    Since the proposed model is based on primary value functions

    discussed in the extant literature, it has similarities with existing

    models, particularly with those of  Schwartz (1992)  and Inglehart

    (1977). Testing similarities with the Schwartz model,   Gouveia

    (2003)  analyzed together the ten motivational types and the six

    basic values. Despite the numerical difference, the motivational

    types were easily identified according to the functional dimen-

    sions. For example, promotion values subsumed Schwartz’s

    achievement and power, normative values incorporated Schwartz’s

    conformity and tradition, while existence values (reflecting sur-

    vival needs) are underrepresented in Schwartz’s value instrument

    and model (see also   Gouveia, Milfont, Fischer, & Schultz, 2007).

    The functional theory also resembles the Inglehart (1977)  model

    as both make a distinction between materialistic/pragmatic versus

    humanitarian/idealistic values. Notwithstanding these similarities,

    the functional theory strikes new conceptual ground by reconciling

    distinct value traditions into a single framework. The proposed

    theory is thus an improvement or refinement of existing models.

    4. Hypotheses and study overview

    The present study further evaluates the usefulness of the func-

    tional theory of values. Building on the theoretical considerations

     just presented, we proposed hypotheses related to the content

    and structure of the value functions. The hypotheses are in line

    with the configuration depicted in Figure 1.

    First, value items used in several measures (e.g.,  Braithwaite &

    Scott, 1991) were selected as the marker values for the six specific

    subfunctions or basic values. We hypothesize that the selected 18

    marker values will be strong indicators of their correspondent ba-

    sic values (Hypothesis 1). Second, the horizontal axis in   Figure 1

    corresponds to the circle of goals (personal, central or social). Wethus predict that values reflecting central goals will be located in

    the center of the multidimensional space, and located on either

    side will be values reflecting personal or social goals (Hypothesis 2a). Finally, the vertical axis corresponds to the level of needs, with

    values expressing survival and thriving needs expected to be pro-

     jected into two separate regions in the proposed two-dimensional

    space (Hypothesis 2b).Besides testing these theoretical hypotheses, the present study

    also assesses the psychometric properties of the Basic Values Sur-

    vey and its appropriateness for measuring the proposed value

    space in a large national sample of Brazilian physicians. Analysis

    of this data has been reported in another publication (Fischer, Mil-

    font, & Gouveia, 2011), but the studies have completely distinct

    aims. While Fischer and colleagues examined the influence of so-

    cial context on the structure of values at an aggregated level (i.e.,

    physicians data grouped within Brazilian states), the present study

    focuses on individual-level analyses, the particular hypotheses de-

    rived from the theory, and the psychometric properties of the Basic

    Values Survey.

    5. Method

    5.1. Participants and instrument 

    The participants were 13,414 physicians (70% males) between

    the ages of 22 and 85 (M  = 40.8, SD  = 10.14) from all 26 Brazilian

    states and the Federal District. Participants completed an online

    questionnaire investigating Brazilian physicians’ professionalcharacteristics, which also included the Basic Value Survey (BVS;

    V.V. Gouveia et al. / Personality and Individual Differences 60 (2014) 41–47    43

    http://-/?-http://-/?-http://-/?-http://-/?-http://-/?-http://-/?-

  • 8/19/2019 Teoria Funcionalista Valores Gouveia(2014)

    4/7

    Gouveia, 2003). The BVS is composed of 18 marker values with two

    brief descriptions presented after each value (see Supplementary

    Online Material). Participants rated each item-value on a 7-point

    scale, ranging from 1 (completely unimportant ) to 7 (of the utmost importance), considering how important each value was for themas a guiding principle in their life.

    The alpha coefficients ranged from .53 (interactive) to .60 (nor-

    mative) (amean

     = .56), and the mean inter-item correlations ranged

    from .28 to .33 (average = .30; see Table S1). Consistent reliability

    indicators were also observed across subsamples from the five

    geo-social regions in Brazil: North,  n = 655; Northeast, n = 2518;Central-West,  n = 1397; Southeast, n  = 6968; and South,  n  = 1876

    (see Table S2). Low alphas are not uncommon in value measures

    (e.g.,   Schwartz, 2005), and these results provide indication of 

    acceptable internal consistency and homogeneity for research pur-

    poses on values. All six basic values were positively correlated, with

    correlations ranging from .12 to .47 (average = .35; see Table S1).

    5.2. Procedure

    The questionnaire was available on the internet for six months.

    Participants had to enter their physician’s register number andbirth date to access the questionnaire. Only registered physicians

    could take part in the study and participants could only complete

    the questionnaire once. Participants’ identification was later dis-

    carded to preserve their anonymity. The average completion time

    was 15 min.

    6. Results

    6.1. Content hypothesis

    To test the content hypothesis, confirmatory factor analyses

    were performed using the covariance matrix among the 18 values

    as input and maximum likelihood estimation procedures in LISREL.

    Standard goodness-of-fit statistics were used to assess model fitand to compare competing models. We tested four alternative

    models against our hypothesized six-factor model. Since the six

    basic values were all positively interrelated, we first tested an

    undifferentiated one-factor latent model with all items. We then

    fitted oblique latent models. The level of needs might be a parsi-

    monious explanation of the value structure; hence we tested a

    correlated two-factor latent model differentiating values express-

    ing survival versus thriving needs. Third, a correlated three-factor

    latent model was tested by differentiating personal, central and so-

    cial values. Finally, we proposed that central values form the core

    of the values structure; therefore, we tested a correlated five-factor

    latent model combining existence and suprapersonal values.

    As can be seen in  Table 1 and  Figure S1, the six-factor model

    without any constraint or change to improve fit was statisticallybetter fitting than other theory-based alternatives. We also cross-

    validated the six-factor model across the five geo-social regions

    in Brazil. Configural equivalence of the six-factor model was

    confirmed (CFI = .91, RMSEA = .08). These results support Hypothe-

    sis 1 and indicate that participants distinguish six basic values as

    measured by the BVS.

    6.2. Structure hypotheses

    To test the structure hypotheses, we first employed a confirma-tory Multidimensional Scaling (MDS) with proximity transforma-

    tions into   z -transformed Euclidean distances with PROXSCAL algorithm in SPSS. Like a confirmatory factor analysis, a confirma-

    tory MDS compares a theoretical model to the observed data; but

    instead of fixing relations between items and factors the researcher

    fixes the coordinates of the observed data in the multidimensional

    space based on the theoretical model.

    The confirmatory MDS was performed by specifying the theo-

    retical structure shown in Figure 1, and then comparing to the fit

    of the observed structure. A two-dimensional structure was im-

    posed in line with the theory and because it best represents the

    dimensionality of the value space (Fontaine et al., 2008). The

    following parameters were specified for the first dimension:

    excitement [1.0], promotion [1.0], existence [0.0], suprapersonal[0.0], interactive [1.0], and normative [1.0]. For the second

    dimension the following parameters were specified: excitement

    [0.5], promotion [0.5], existence [1.0], suprapersonal [1.0],

    interactive [0.5], and normative [0.5]. Tucker’s coefficient of con-

    gruence (also known as Tucker’s phi) was used as a measure of 

    model fit, with values higher than .90 indicating good fit ( van de

    Vijver & Leung, 1997).

    Figure 2a and 2b respectively show the results of the uncon-

    strained and confirmatory MDS. The unconstrained solution clearly

    shows that the personal-central-social distinction was more well-

    defined than the survival-thriving distinction. Nevertheless, the

    Tucker’s phi of .98 indicates that forcing the location of the marker

    values to fit the theoretical structure provides good fit.

    We then ran a generalized procrustes analysis in the GPA soft-

    ware (Commandeur, 1991) and Orthosim (Barrett, 2005) to com-

    pare the coordinates of the unconstrained and confirmatory MDS

    configurations (see Table S3), with values close to .90 or higher

    indicating acceptable fit. The total fit between the configurations

    was .81. In line with   Figure 2a, the double-scaled Euclidean

    similarity coefficient showed that the first dimension had a better

    congruence match (.90) than the second dimension (.55). These re-

    sults confirm Hypothesis 2a: central values were located between

    personal and social values. Less support was observed for Hypoth-

    esis 2b suggesting that survival and thriving values are separated

    into two regions.

    were selected – values guide actions and express needs – and a

    three-by-two framework was proposed based on their interplay.The three-by-two framework yields six basic values (existence,

    promotion, normative, suprapersonal, excitement, and interactive)

    and marker values were selected from the values literature asobserved indicators. Theoretical hypotheses were supported in a

    large national Brazilian sample of physicians. The theory has been

    previously tested with student populations (Gouveia, Milfont, &

    Fischer, submitted) and outside Brazil (Ardila, Gouveia, & Medei-

    ros, 2012; Gouveia et al., 2010), but the present study provides

    the first empirical test of the three-by-two framework in a national

    sample constituted exclusively by non-students.

    The prediction that the 18 marker values would be good indica-

    tors of their corresponding theoretical basic values was confirmed.

    This finding provides support for the Basic Values Survey as a psy-

    chometrically-sound measure for assessing the proposed theoreti-

    cal model. Instead of having an extensive list of values and then

    creating value dimensions  ex post facto   based on empirical data,

    the proposed framework was theoretically driven and determined

    beforehand, and only then were the specific marker values selected

    to represent the proposed dimensions.

    Besides providing a more parsimonious and theory-driven ap-

    proach, this procedure also means that researchers could select

    other value markers as indicators of the core basic values. Indeed,

    it seems more reasonable to work with the core basic dimensions

    of values, avoiding specific and less fundamental facets – an ap-

    proach that has been supported by others (Strack & Dobewall,

    2012). Although researchers are encouraged to select and use dis-

    tinct marker values, the findings reported in the present study and

    others (Gouveia, 2003; Gouveia, Milfont, & Fischer, submitted) pro-

    vide strong empirical support for the use of the Basic Value Survey

    as a tool for testing the functional theory.

    In line with the theoretical model depicted in  Figure 1, values

    focusing on central goals are located between values with personal

    and social goals. The prediction that values expressing survival and

    thriving needs are projected into two separate regions in the two-

    dimensional space was not fully supported. Results using the same

    dataset (Fischer et al., 2011) as well as other values research (Fon-

    taine et al., 2008) have shown that the dimension representing

    personal versus social values is relatively more stable than the

    dimension representing survival versus thriving values. These find-

    ings combined with the nature of the present sample could explain

    this unexpected result.Overall, the empirical evidence accumulated so far strongly sug-

    gests that the two functional dimensions and the six basic values

    resulting from their interplay can parsimoniously explain the

    structure of the value space. Going beyond earlier studies showing

    that motivational systems are organized in a two-dimensional

    structure (Fontaine et al., 2008; Grouzet et al., 2005; Ronen,

    1994), the theory is the first to explicitly propose the functional

    interplay between the two dimensions. The usefulness of the

    theory has also been shown by initial studies using the model to

    predict external variables, including sexual liberalism (Guerra

    et al., 2012) and organizational commitment (Gouveia, Milfont,

    Fischer, & Coelho, 2009).

    Future studies should attempt to test the functional theory in a

    broad cross-cultural sample, and also test the usefulness of themodel in predicting other criterion variables. Future studies should

    also attempt to test other hypotheses derived from the theory, in

    particular the compatibility and congruence hypotheses (Gouveia,

    2013). Drawing from two primary functions values fulfill, and

    providing a parsimonious and theory-driven account of the value

    domain, the functional theory of values improves upon current

    dominant value models. We believe the functional theory is an

    additional theoretical tool for understanding the structure of the

    value domain.
