Social physique anxiety and physical activity: A self-determination theory perspective

ObjectiveUsing self-determination theory [Deci, E. L., & Ryan, R. M. (1985). Intrinsic motivation and self-determination in human behavior. New York, NY: Plenum Press; Ryan, R. M., & Deci, E. L. (2002). An overview of self-determination theory: an organismic-dialectical perspective. In E. L. Deci, & R. M. Ryan, (Eds.), Handbook of self-determination research (pp. 3–33). Rochester, NY: University of Rochester Press.] as a framework, this study examined the relationships between social physique anxiety (SPA) and physical activity-related psychological needs, motivation, and reported behavior.MethodThree hundred and eighty one males and females (M_age = 18.69, SD = 1.15) completed a self-administered questionnaire package.ResultsResults revealed a good measurement model for the total sample (χ² = 592.52; df = 238; RMSEA = .063; CFI = .94; SRMR = .05) and multi-group invariance indicated that the male and female measurement models were comparable. The structural model was adequate for the total sample (χ² = 638.69; df = 243; RMSEA = .065; CFI = .94; SRMR = .06) and accounted for 36% of the variance in reported physical activity behavior. In addition, the structural model was partially gender invariant.ConclusionsFindings supported the proposed motivational sequence in which SPA directly influenced need satisfaction, and indirectly influenced physical activity motivation and behavior. From a practical perspective, interventions aimed at decreasing SPA may be helpful in promoting physical activity motivation and behavior.     

Reporting of Subscores Using Multidimensional Item Response Theory

Recently, there has been increasing interest in reporting subscores. This paper examines reporting of subscores using multidimensional item response theory (MIRT) models (e.g., Reckase in Appl. Psychol. Meas. 21:25–36, 1997; C.R. Rao and S. Sinharay (Eds), Handbook of Statistics, vol. 26, pp. 607–642, North-Holland, Amsterdam, 2007; Beguin & Glas in Psychometrika, 66:471–488, 2001). A MIRT model is fitted using a stabilized Newton–Raphson algorithm (Haberman in The Analysis of Frequency Data, University of Chicago Press, Chicago, 1974; Sociol. Methodol. 18:193–211, 1988) with adaptive Gauss–Hermite quadrature (Haberman, von Davier, & Lee in ETS Research Rep. No. RR-08-45, ETS, Princeton, 2008). A new statistical approach is proposed to assess when subscores using the MIRT model have any added value over (i)  the total score or (ii)  subscores based on classical test theory (Haberman in J. Educ. Behav. Stat. 33:204–229, 2008; Haberman, Sinharay, & Puhan in Br. J. Math. Stat. Psychol. 62:79–95, 2008). The MIRT-based methods are applied to several operational data sets. The results show that the subscores based on MIRT are slightly more accurate than subscore estimates derived by classical test theory.     

National IQs predict educational attainment in math,reading and science across 56 nations

The results of the 2006 PISA (Program for International Student Assessment) study of reading comprehension, mathematical ability, and science understanding administered to 15 year olds in 56 countries [OECD (2007). PISA 2006: Science Competencies for Tomorrow's World. Paris: OECD.] are examined to assess the predictive validity of the national IQs presented by Lynn and Vanhanen [Lynn, R., & Vanhanen, T. (2002). IQ and the wealth of nations. Westport, CT: Praeger., Lynn, R., & Vanhanen, T. (2006). IQ and global inequality. Augusta, GA: Washington Summit Books.], and to assess the contributions of national differences in IQ and educational variables to national differences in educational attainment. It was found that national scores in reading comprehension, mathematical ability, and science understanding are correlated with Lynn & Vanhanen (L & V) national IQs at 0.84; corrected for attenuation, 0.935. This establishes the high validity of Lynn & Vanhanen national IQs. The contribution of national differences in IQ and education variables to national differences in educational attainment obtained in the 2006 PISA 56 nation study showed that the predictive validity of IQ alone was 0.84, and that national IQs together with one economic and two education variables had the validity 0.90 in predicting PISA 2006 results.

Anxiety and Depression in Brazilian Orthopaedics Inpatients: A Cross Sectional Study with a Clinical Sample Comparison

There are few studies on the development of anxiety and depression in orthopaedics and trauma (O&T) inpatients. We designed a cross-sectional study aimed at comparing the prevalence of depression and anxiety in 100 O&T inpatients and 100 clinical inpatients in the same hospital. O&T patients were divided into subgroups: trauma and non-trauma (arthroplasty, tumour, and infection sub grouping). We measured anxiety and depression by the Hospital Anxiety and Depression Scale and co-morbidities by the Charlson age-adjusted comorbidity index (CCI). For the trauma subgroup, AO/OTA fracture classification and Gustillo and Anderson grade of open fractures classification was applied. The prevalence of anxiety and depression was 35% and 28%, respectively for the clinical sample, and 44% and 33% for the O&T sample. Compared with the clinical sample, anxiety scores were higher in the O&T sample (p = .047), and in arthroplasty (p = .020) and trauma subgroups (p = .031). In the O&T sample, high CCI scores were associated with high anxiety scores (p = .033).

Common and Specific Dimensions of Self-Reported Anxiety and Depression in Adolescent Outpatients

To investigate the common and specific dimensions of anxiety and depression in adolescents, the Beck Anxiety Inventory (BAI; Beck, A. T., & Steer, R. A. Manual for the Beck Anxiety Inventory. San Antonio, TX: Psychological Corporation 1993a) and Beck Depression Inventory-II (BDI-II; Beck, A. T., Steer, R. A., & Brown, G. K. Manual for Beck Depression Inventory (2nd Ed.). San Antonio, TX: Psychological Corporation 1996) were administered to 840 adolescent (13–17 years old) outpatients who were diagnosed with various types of psychiatric disorders. A Schmid-Leiman transformation was used with the iterated-principal-factor pattern matrix of the BAI and the BDI-II loadings. The amounts of orthogonalized common variance that were explained by the one second-order (56%), one first-order depression (22%), and two first-order anxiety (22%) dimensions were comparable to those previously reported for adult psychiatric outpatients. The results were discussed as supporting the construct of negative affectivity that is proposed in L. A. Clark and Watson’s (1991) tripartite model of anxiety and depression.

The Impact of Performance-Contingent Rewards on Perceived Autonomy and Competence

Two studies examined the impact of performance-contingent rewards on perceived autonomy, competence, and intrinsic motivation. Autonomy was measured in terms of both decisional and affective reports. The first study revealed an undermining effect of performance-contingent rewards on affective reports of autonomy among university students, and an increase in reports of competence. Decisional autonomy judgements were unaffected by rewards. The second study replicated this pattern of findings among elementary school children. These results help resolve Cognitive Evaluation Theory's (E. L. Deci & R. M. Ryan, 1985; R. M. Ryan, V. Mims, & R. Koestner, 1983) and Eisenberger, Rhoades, et al.'s (R. Eisenberger, L. Rhoades, & J. Cameron, 1999) divergent positions on the impact of performance-contingent rewards on autonomy. The studies also included measures of intrinsic motivation.

Psychometric Measures of Boredom: A Review of the Literature

This research presents a review of the psychometric measures on boredom that have been developed over the past 25 years. Specifically, the author examined the Boredom Proneness Scale (BPS; R. Farmer & N. D. Sundberg, 1986), the job boredom scales by E. A. Grubb (1975) and T. W. Lee (1986), a boredom coping measure (J. A. Hamilton, R. J. Haier, & M. S. Buchsbaum, 1984). 2 scales that assess leisure and free-time boredom (S. E. Iso-Ahola & E. Weissinger, 1990; M. G. Ragheb & S. P. Merydith, 2001), the Sexual Boredom Scale (SBS; J. D. Watt & J. E. Ewing, 1996), and the Boredom Susceptibility (BS) subscale of the Sensation Seeking Scale (M. Zuckerman, 1979a). Particular attention is devoted to discussing the literature regarding the psychometric properties of the BPS because it is the only full-scale measure on the construct of boredom.

Machiavellianism and sexual behavior: Motivations,deception and infidelity

The current study investigated the influence of Machiavellianism, a personality trait characterized by a manipulative interpersonal style and willingness to exploit others (Christie & Geis, 1970), on three areas of sexual behavior. Men (N = 90) and women (N = 192) aged 18–81 years (M = 25.82, SD = 9.85) completed the Mach IV (Christie & Geis, 1970), YSEX Questionnaire (Meston & Buss, 2007), Sexual Deception Scale (Marelich, Lundquist, Painter, & Mechanic, 2008) and Intentions Towards Infidelity Scale (Jones, Olderbak, & Figueredo, 2011). Those with high levels of Machiavellianism were more likely to engage in sexual behavior for physical reasons, goal attainment and insecurity. In particular, Machiavellian men and women endorsed stress reduction, experience seeking, resources, social status, revenge, utilitarian reasons, boosting self-esteem, duty/pressure, and mate guarding as motivations for sexual behavior. Machiavellianism was also a significant predictor of each form of sexual deception investigated (blatant lying, self-serving and avoiding confrontation) and intentions to engage in infidelity. Sex did not moderate the influence of Machiavellianism on sexual behavior.

Relations between multidimensional perfectionism and burnout in junior-elite male athletes

ObjectivesThe purpose of the present investigation was to examine the moderating influence of perceptions of goal progress and achievement goal orientations on the relationship between multidimensional perfectionism and athlete burnout.Methods201 junior-elite male athletes, ranging from 11 to 21 years of age (M = 15.64, SD = 1.92), were recruited from professional sport clubs in the UK and completed a multi-section inventory assessing self-oriented and socially prescribed perfectionism [Hewitt, P. L., & Flett, G. L. (1991). Perfectionism in the self and social contexts: conceptualization, assessment, and association with psychopathology. Journal of Personality and Social Psychology, 60, 456–470], achievement goal orientations [Roberts, G. C., Treasure, D. C., & Balague, G. (1998). Achievement goals in sport: the development and validation of the perception of success questionnaire. Journal of Sport Sciences, 16, 337–347], perceived goal progress [Hill, A. P., Hall, H. K., Appleton, P. R., & Kozub, S. A. (2008). Perfectionism and burnout in junior-elite soccer players: the mediating influence of unconditional self-acceptance. Psychology of Sport and Exercise, 9, 630–644] and multidimensional athlete burnout [Raedeke, T. D., & Smith, A. L. (2001). Development and preliminary validation of an athlete burnout measure. Journal of Sport and Exercise Psychology, 23, 281–306].ResultsRegression analyses revealed that socially prescribed perfectionism demonstrated a significant positive association, and self-oriented perfectionism a significant negative association with burnout dimensions. However, the hypotheses for moderation of the perfectionism–burnout relationship were not supported.ConclusionsOverall, while there was no evidence to support the hypothesised moderation of the perfectionism–burnout relationship, the results provide support for a growing body of literature which indicates that maladaptive forms of perfectionism may contribute to burnout in elite junior athletes [Chen, L.

Age and walking conditions differently affect domains of gait

IntroductionAnalysing gait in controlled conditions that resemble daily life walking could overcome the limitations associated with gait analysis in uncontrolled real-world conditions. Such analyses could potentially aid the identification of a walking condition that magnifies age-differences in gait. Therefore, the aim of the current study was to determine the effects of age and walking conditions on gait performance.MethodsTrunk accelerations of young (n = 27, age: 21.6) and older adults (n = 26, age: 68.9) were recorded for 3 min in four conditions: walking up and down a university hallway on a track of 10 m; walking on a specified path, including turns, in a university hallway; walking outside on a specified path on a pavement including turns; and walking on a treadmill. Factor analysis was used to reduce 27 computed gait measures to five independent gait domains. A multivariate analysis of variance was used to examine the effects of age and walking condition on these gait domains.ResultsFactor analysis yielded 5 gait domains: variability, pace, stability, time & frequency, complexity, explaining 64% of the variance in 27 gait outcomes. Walking conditions affected all gait domains (p < 0.01) but age only affected the time & frequency domain (p < 0.05). Age and walking conditions differently affected the domains variability, stability, time & frequency. The largest age-differences occurred mainly during straight walking in a hallway (variability: 31% higher in older adults), or during treadmill walking (stability: 224% higher, time&frequency: 120% lower in older adults).ConclusionWalking conditions affect all domains of gait independent of age. Treadmill walking and walking on a straight path in a hallway, were the most constrained walking conditions in terms of limited possibilities to adjust step characteristics. The age by condition interaction suggests that for the gait domains variability, stability, and time & frequency, the most constrained walking conditions seem to magnify the age-differences in gait.
