    Although perfectionism is often associated with increased occupational stress, little research has

    explored the differential roles of adaptive (positive perfectionism [PP]) and maladaptive (negative

    perfectionism [NP]) perfectionism in predicting psychological responses to stressors. Applying the

    Holistic Model of Stress, this study examined the role of perfectionism in explaining positive (eustress)

    and negative (distress) stress responses, as indicated by vigor and strain. Participants were 156 employ-

    ees (73 academic, 83 administrative) from a tertiary institution who completed self-report question-

    naires, consisting of the Positive and Negative Perfectionism Scale, Personal Strain Questionnaire

    (involving vocational, psychological, interpersonal, and physical strain), Shirom-Melamed Vigor Measure,

    and Marlowe-Crowne Social Desirability Scale. Correlations and hierarchical multiple regressions

    assessed how PP and NP predicted vigor and strain. After controlling for social desirability, higher PP

    predicted greater vigor, and lower vocational and physical strain; whereas higher NP predicted less vigor,

    and greater vocational, psychological, interpersonal, and physical strain. Therefore, PP and NP are evi-

    dently different in the understanding of responses to stressors. Promoting PP may aid in lowering strain

    perceptions associated with ones job and body. Interventions to cope with increased NP could improve

    overall well-being.

    1. Introduction

    Perfectionism is an achievement-based behavioural characteris-

    tic defined as the setting of excessively high performance

    standards and overly critical evaluations of ones behaviour (Frost,

    Marten, Lahart, & Rosenblate, 1990). Convergence in theory and

    data on the nature of perfectionism has distinguished between

    two major types of perfectionism: Adaptive and maladaptive per-

    fectionism (Slade & Owens, 1998). The former is a predominantly

    normal behavioural characteristic which benefits the individual,

    whereas the latter is pathological and predictive of maladaptive

    behaviours. Although there are many ways in which the subtypes

    of perfectionism have been defined and debated (e.g., Gaudreau &Thompson, 2010), this study applied the theoretically-sound

    delineation of Positive (PP) and Negative (NP) Perfectionism to

    exemplify adaptive and maladaptive perfectionism, respectively.

    This distinction rests on Skinners reinforcement theory: Despite

    being overtly similar behaviours, PP refers to the cognitions and

    behaviours directed towards achieving high-level goals as driven

    by positive reinforcement and a desire for success, whereas NP re-

    fers to those driven by negative reinforcement and a fear of failure.

    Together, PP and NP form a dual process model of perfectionism

    (Slade & Owens, 1998).

    Past research has revealed positive relationships between PP

    and adaptive behaviours as well as between NP and maladaptive

    behaviours in various contexts, including eating problems (Chan,

    Ku, & Owens, 2010), motivation and affect (Bergman, Nyland, &

    Burns, 2007), and neurocognitive performance (Slade, Coppel, &

    Townes, 2009). Although perfectionism in itself, or when defined

    using other scales, has often been shown to relate to increased

    stress among daytime employees (Childs & Stoeber, 2010), few

    occupational health studies have applied the PPNP distinction

    when examining the perfectionism-stress links. Moreover, virtu-ally no study has linked PP and NP to adaptive and maladaptive as-

    pects of occupational stress simultaneously. Besides providing a

    strong theoretical basis to explain any predictive differences be-

    tween the perfectionism dimensions, this design can be useful to

    explore the multidimensionality of perfectionism in the context

    of positive and negative responses to workplace stressors. This

    study applied the Holistic Model of Stress (Nelson & Simmons,

    2003), which examines how individual differences, including

    perfectionism, simultaneously predict positive and negative

    psychological responses to stressors. The positive response, eus-

    tress, is the extent to which the cognitive appraisal of a situation

    is perceived to enhance well-being; whereas its negative

    counterpart, distress, is the extent to which the appraisal of a

    situation decreases well-being.

    In this study, the role of perfectionism in predicting eustress

    and distress was assessed among a group of university employees.

    Studies among academic and administrative university employees

    have revealed rising stress levels over the past three decades

    (Abouserie, 1996; Gmelch, Wilke, & Lovrich, 1986; Watts & Robert-

    son, 2011). University employees experience significant stressorsfrom many different areas of work, including time constraints, stu-

    dent interaction, teaching responsibilities, and research demands.

    This may render them more susceptible to perfectionism and its

    associated behaviours, since there are more areas of work in which

    they may set high-level goals. Thus, studying a potential group of

    perfectionists among university employees may amplify the per-

    fectionismstress relationships, in addition to further understand-

    ing the behavioural characteristics that can predict occupational

    stress within this population. University employees have previ-

    ously reported various health problems, strained relationships,

    poorer quality of life, along with a decrease in teaching and re-

    search quality, job satisfaction and organisational commitment,

    due to occupational stress (Gillespie, Walsh, Winefield, Dua, &

    Stough, 2001); but the role that PP and NP might play remains

    unclear.

    Not surprisingly, researchers have looked at relationships be-

    tween perfectionism and occupational stress in universities, but

    the literature is scarce. Only two studies among academic staff,

    in which perfectionism subtypes were delineated differently, were

    found: One study conducted with university professors revealed

    positive relationships between maladaptive perfectionism and

    anxiety, depression, and hostility (Dunn, Whelton, & Sharpe,

    2006). In contrast, another study found that adaptive and maladap-

    tive perfectionism predicted lower research productivity among

    professors, implying that both dimensions were maladaptive.

    These contradictory results may arise due to the difficult nature

    of the academic workplace, which commonly involves criticism,

    scrutiny, and rejection; such could lead perfectionists (regardless

    of type) to reduce their exposure to these threats by lowering theirresearch output (Sherry, Hewitt, Sherry, Flett, & Graham, 2010).

    Dunn et al. (2006) also noted that academic staff often perform

    demanding and detailed work subjected to critical peer scrutiny

    in largely difficult and unsupportive environments, which can

    exacerbate the maladaptive nature of perfectionism. It is therefore

    worth investigating whether adaptive and maladaptive perfection-

    ism have differential predictions of occupational stress among a

    potential group of perfectionists in the university workplace.

    Moreover, adaptive behaviours in response to stressors have not

    been examined when studying relationships between perfection-

    ism and stress among university employees; doing so could shed

    more light on the potentially adaptive nature of perfectionism in

    the context of occupational health.

    This study employed strain, which is closely related to job burn-out (Higgins, 1986), to indicate distress. Strain is the negative reac-

    tion that develops from the inability to cope effectively with

    various stressors (Osipow, 1998), which may manifest in various

    areas of life other than work, such as in psychological functioning,

    interpersonal relationships, and physical health. Numerous studies

    have established the positive association between perfectionism

    and burnout among employees (e.g.,Childs & Stoeber, 2010). Com-

    pared with burnout, strain indicates less extreme points of distress,

    and offers a more comprehensive assessment (i.e., covering

    distress in vocational, psychological, interpersonal, and physical

    aspects), thus offering more valuable information for the purpose

    of occupational health interventions. To indicate eustress, vigor,

    one of strains positive counterparts, was measured: This is the

    energy resource related to the motivational processes that initiateand sustain behaviour at work (Shirom, 2003). Vigor is thus

    pertinent to the dual process model of perfectionism since individ-

    uals with high PP are motivated to achieve success, whereas

    individuals with high NP are motivated to avoid failure (Slade &

    Owens, 1998).

    Consistent with the Holistic Model of Stress, two studies have

    examined how perfectionism may predict burnout (distress) and

    vigor (eustress) among undergraduates (Zhang, Gan, & Cham,

    2007) and various daytime employees (across public, retail, andlaw sectors;Childs & Stoeber, 2010). Again, different delineations

    of perfectionism were used in these studies. Overall, greater adap-

    tive perfectionism was found to predict lower burnout and higher

    vigor, whereas increased maladaptive perfectionism predicted

    higher burnout and lower vigor. The main hypotheses of the pres-

    ent study built upon these findings: The aim was to examine how

    the dual process model of PP and NP may predict strain and vigor

    among daytime employees. The measurement of strain included

    vocational, psychological, interpersonal, and physical strain; thus

    facilitating a broader assessment of distress. This study also inves-

    tigated the factor structure of perfectionism in a relatively homog-

    enous group of daytime employees, hypothesising that two distinct

    factors of perfectionism would emerge, representing the dual

    distinction.

    2. Methods

    2.1. Participants

    Participants were 156 employees (nmale= 64, nfemale= 92) at a

    university, ranging from 20 to 67 years old (M= 35.00 years,

    SD= 9.30 years), with a reasonable balance between academic

    (n= 73) and administrative staff (n= 83). Duration of employment

    ranged from 2 weeks to 14 years (M= 2.7 years,SD= 2.8 years) and

    most were working full-time (87.1%). A sample size ofN= 107 was

    needed to attain a power of .80 to detect a medium effect size on

    the main analyses.

    2.2. Measures

    2.2.1. Perfectionism

    The 40-item Positive and Negative Perfectionism Scale (PANPS;

    Terry-Short, Owens, Slade, & Dewey, 1995) was used to assess

    participants PP and NP levels (20 items each, shown inTable 1).

    Participants indicated the extent to which they agreed with each

    item on a Likert scale from 1 (strongly disagree) to 5 (strongly agree).

    PP and NP scores were obtained by summing the 20 item ratings;

    higher scores indicated higher levels of perfectionism. In the pres-

    ent sample, PP (a= .84) and NP (a= .88) showed high internalconsistency.

    2.2.2. StrainThe 40-item Personal Strain Questionnaire (PSQ) from the Occu-

    pational Stress Inventory-Revised (Osipow, 1998) was employed to

    measure strain. There are 4 subscales (10 items each), covering

    vocational (e.g., I am bored with my work.), psychological (e.g.,

    Lately, I am easily irritated.), interpersonal (e.g., I often argue

    with friends.), and physical strain (e.g., Lately, I have been tired.).

    Participants rated how often each item was true on a Likert scale

    from 1 (rarely or never true) to 5 (true most of the time). Subscale

    scores were sums of the respective subscale item ratings; higher

    scores indicated greater strain. All four subscales demonstrated

    satisfactory internal consistency in this study (a= .70.89).

    2.2.3. Vigor

    Vigor was measured using the 12-item Shirom-Melamed VigorMeasure (SMVM;Shirom, 2005). It comprises 3 subscales: Physical

    strength (5 items; e.g., I feel energetic.), cognitive liveliness (3

    items; e.g., I feel I can think rapidly.), and emotional energy (4

    items; e.g., I feel able to show warmth to others.). Participants

    indicated the frequency of experiencing each item over the last

    30 workdays, using a Likert scale, from 1 (never or almost never)

    to 7 (always or almost always). Scores were summed, with higher

    scores indicating greater vigor. The SMVM showed high internal

    consistency in this study (a= .91).

    2.2.4. Social desirability

    The Marlowe-Crowne Social Desirability Scale (MCSDS;Crowne

    & Marlowe, 1960) was included to control for potential response

    bias arising from the tendency towards socially desirable behav-

    iour and denial of socially undesirable traits. Respondents indi-

    cated whether each item was true or false for them. Out of 33

    items, 18 are attribution items (e.g., I have never intensely disliked

    anyone.) and 15 are denial items (e.g., I like to gossip at times.).

    Scores were the addition of true responses for attribution items

    and false responses for denial items; higher scores implied a great-

    er tendency to respond in a socially desirable manner. The MCSDS

    demonstrated satisfactory internal consistency in this sample(a= .72).

    2.3. Procedure

    Ethical approval was obtained through the universitys human

    research ethics committee. A call for participation was sent to all

    university employees through flyers, broadcast emails, email

    newsletters, and the universitys website. Interested employees

    contacted the researcher to attend a testing session. Twenty

    lunch-hour sessions, each lasting about 40 minutes, were con-

    ducted on university premises over the course of 7 weeks. At the

    session, each participant was given an explanatory statement, a

    consent form, and a coded questionnaire. They were briefed on

    the voluntary and confidential nature of the study, the need for

    their informed consent, and the materials. Each participant re-

    ceived a packed lunch upon returning the completed questionnaire

    and consent form.

    2.4. Analyses

    A principal components analysis (PCA) was conducted on the

    PANPS to examine its factor structure in this sample. Correlations

    and hierarchical multiple regressions were then used to investigatethe relationships between PP and NP with strain and vigor.

    Statistical significance was set at p < .05 (two-tailed). For each

    regression, social desirability was entered in the first step, with

    PP and NP entered in the second step.

    3. Results

    3.1. PANPS factor structure

    Assumption checks on the 40 PANPS items revealed reasonably

    linear interrelationships and no outliers. The data were also suit-

    able for factor analysis, with the correlation matrix showing many

    correlation coefficients above .30. The Kaiser-Meyer-Olkin measure

    of sampling adequacy was .80 and Bartletts Test of Sphericity

    showed statistical significance,p < .001.

    The two-component solution explained a total of 32.6% of the

    total variance, with Component 1 contributing 22.6% and Compo-

    nent 2 contributing 10.0%. The rotated Varimax solution inTable 1

    illustrates a number of moderately strong loadings, with most

    items loading substantially on one component. Consistent with

    the PANPS development study (Terry-Short et al., 1995), items

    loading strongly on the first and second components referred to

    perfectionism as a function of negative reinforcement and positivereinforcement, respectively. The weak correlation between the

    components (r = .26) suggests they measure largely different and

    independent dimensions.

    3.2. Perfectionism, strain, and vigor hypotheses

    No violations of multicollinearity, normality, linearity, homo-

    scedasticity, and independence of residuals assumptions were

    found. Two outliers were detected, so data from these cases were

    removed from subsequent analyses. Table 2 displays the correla-

    tions between PP and NP with vigor and vocational, psychological,

    interpersonal, and physical strain. PP only showed a weak negative

    correlation with vocational strain; whereas NP showed moderatelystrong, positive correlations with all strain variables, and a weak

    negative relationship with vigor.

    Table 3 summarises the hierarchical multiple regression

    statistics when PP and NP were entered in the second step. After

    controlling for social desirability, PP and NP accounted for 12% to

    23% (ps < .001) of the variances in vocational, psychological, inter-

    personal, and physical strain, and vigor. Increased PP significantly

    predicted lower vocational and physical strain, and higher vigor.

    However, PP did not predict less psychological and interpersonal

    strain. In contrast, increased NP predicted higher vocational,

    psychological, interpersonal, and physical strain, and lower vigor.

    Note that after PP and NP were entered in the regressions, social

    desirability remained significant in predicting vocational, psycho-

    logical, and physical strain.

    4. Discussion

    Consistent with the dual process model of perfectionism and

    Terry-Short et al.s (1995)original findings, the present data re-

    vealed two independent, distinct factors, replicating similar factor

    structures found in other studies (e.g.,Chan & Owens, 2006). More-

    over, PP and NP offered differential predictions of strain and vigor

    among university employees, supporting the notion that one sub-scale is adaptive and the other maladaptive, consistent withSlade

    and Owens (1998) dual process model. This contrasted with

    Sherry et al.s (2010)findings that both adaptive and maladaptive

    perfectionism dimensions were maladaptive (i.e., predicting lower

    research productivity). This discrepancy could be attributed to

    their use of the Multidimensional Perfectionism Scale (MPS;

    Hewitt & Flett, 1991) and hence a different classification of perfec-

    tionism altogether: In the MPS, the dimension broadly labelled as

    adaptive perfectionism (i.e., Self-Oriented Perfectionism) reflects

    a counterproductive form of over-striving, involving the compul-

    sive need to avoid failure (negative reinforcement) instead of a

    high need for achievement (positive reinforcement). Theoretical

    and empirical evidence also exist for the maladaptive nature of

    Self-Oriented Perfectionism (Owens & Slade, 2008).

    Another reason for the discrepancy may be that the present

    sample of academic and administrative staff, assumed to be repre-

    sentative of daytime university employees, may have lower NP

    when compared withSherry et al.s (2010) sample of professors.

    Although PP and NP were presently shown to be largely indepen-

    dent, other studies with clinical samples have found that the

    benefits of adaptive perfectionism may only be evident when the

    maladaptive component is relatively low (Davis, 1997). Thus,

    interactions may exist between adaptive and maladaptive perfec-

    tionism for employees who might be particularly prone to experi-

    encing the maladaptiveness of perfectionism (Dunn et al., 2006),

    but not in more general employee samples. Note, however, that

    present authors do not intend to imply pathological maladaptive

    perfectionism levels among academic staff; rather, this discussion

    suggests that future research compare PP and NP levels, and testthe PPNP interactions, across clinical and employee samples.

    This study offers empirical evidence for the differential predic-

    tions of PP and NP on strain and vigor that are consistent with past

    studies (Childs & Stoeber, 2010; Zhang et al., 2007). These findings

    support the literature on the Holistic Model of Stress, in which

    perfectionism (individual differences) can simultaneously predict

    strain (distress) and vigor (eustress). Present contributions, none-

    theless, lie in the utility of Skinners reinforcement theory in inter-

    preting these relationships: Differences in strain and vigor levels

    among employees are related to whether their perfectionistic

    behaviour is driven by positive or negative reinforcement. Employ-

    ees who over-strive and set high-level goals out of a desire for

    excellence showed greater vigor, and lower vocational and physical

    strain. In contrast, those who over-strive to avoid failure showed

    less vigor, and were more vulnerable to vocational, psychological,

    interpersonal, and physical strain.

    A plausible reason why NP proves to be maladaptive (i.e., indi-

    viduals with higher NP experience less favourable stress re-

    sponses) is that negative perfectionists can never be certain that

    failure will not occur (Slade & Owens, 1998). Dittner, Rimes, and

    Thorpe (2011) explained that when facing stressors, the negativeperfectionists emphasis on avoiding failure may encourage behav-

    ioural (e.g., working longer hours) and cognitive (e.g., increased

    rumination about work performance) coping responses that lead

    to poor outcomes including fatigue (physical strain) and depres-

    sion (psychological strain). In contrast, the role of PP in predicting

    more favourable stress responses augments the literature on the

    adaptive nature of PP among daytime employees. The focus of po-

    sitive perfectionists is on achieving high-level goals, which is not

    impossible; with little repercussion if they fail to achieve their

    goals because there is no excessive fear of failure (Slade & Owens,

    1998).

    Possibly, PP predicted lower vocational and physical strain but

    not psychological and interpersonal strain because when

    compared with work achievements and physical health, employeesmay be less likely to view psychological well-being and good inter-

    personal relationships as reinforcements or goals to be achieved.

    Deficits in psychological functioning and interpersonal relation-

    ships are not always readily measurable, making them less of a

    priority, especially when facing a stressful workplace and when

    work-related stress becomes a significant part of life (e.g.,

    Abouserie, 1996). In contrast, work achievements and health are

    commonly measured in performance appraisals and medical

    examinations, which have objective indicators of success. Employ-

    ees with high PP may therefore over-strive for excellent appraisals

    and to be disease-free, but not necessarily for psychological well-

    being and good relationships. Another reason could be the

    presence of mediating and moderating variables in the PPstrain

    relationships, which is beyond the scope of this study. Futureinvestigations of potential mediators and moderators may help ex-

    plain the significant relationships between PP with some areas of

    strain and lack thereof with other areas.

    One methodological limitation is that workplace stressors in the

    university were not examined. Although both academic and

    administrative staff have shown high stress levels, they might

    experience different workplace stressors, some of which may act

    to moderate their stress responses (Gillespie et al., 2001). Future

    research can investigate and control for the type and severity of

    stressors when examining how perfectionism predicts eustress

    and distress. Another limitation is that universities typically

    experience a 12-week cycle each semester, with potentially time-

    varying stress levels (e.g., participants sampled earlier in the

    semester may report higher vigor than those sampled later).Although present authors arranged the testing sessions such that

    similar numbers of participants were recruited each week, future

    researchers should note this seasonal effect when studying stress

    responses among university employees. There may also be recipro-

    cal relationships between perfectionism with strain and vigor

    which were not considered: Experiences of strain and vigor could

    also reinforce employees for their perfectionistic behaviours. A

    longitudinal approach may further investigate theoretical and

    empirical support for this notion.To conclude, PP and NP were found to be two distinct subtypes

    of perfectionism which predicted strain and vigor levels differently

    among university employees. Implications include creating aware-

    ness on how different motivations underlying overtly similar per-

    fectionistic behaviours may predict more, or less, favourable stress

    experience at work. Moreover, interventions can explore whether

    enhancing the adaptive PP and developing coping strategies to deal

    with the maladaptive NP may reduce strain and increase vigor.

    Employees experiencing strain associated with work and health

    may benefit from setting high-level goals to achieve success rather

    than to avoid failure. Universities can also consider using PP and

    NP as predictors of future vigor and strain experiences. To this

    end, the PANPS can be administered to assess PP and NP levels

    among employees. Present results may also be broadly applied toperfectionistic daytime employees in other workplace settings,

    although further research is warranted.
