Evaluating validity and test-retest reliability in four drive for muscularity questionnaires

The current study assessed relationships among four commonly used drive for muscularity questionnaires, along with their 7 and 14 day test-retest reliability. Sample 1 was comprised of young British adult males (N=272; M(AGE)=20.3) who completed the questionnaires once. Sample 2, a group of young British adult males (N=54, M(AGE)=19.3), completed the questionnaires three times spaced 7 and 14 days apart. Correlations among Sample 1 ranged from .20 to .82 providing evidence for concurrent and discriminant validities. Evidence for test-retest reliability emerged with intraclass correlations ranging from .78 to .95 (p<.001) and generally nonsignificant t-tests (p>.05). Overall, the data support the psychometric properties of the drive for muscularity inventories; however, the shared variance (35-67%) hints that refinement is possible.     

Psychometric properties of the Revised Male Body Attitudes Scale among Irish men

The psychometric properties of a revised version of the Male Body Attitudes Scale (Tylka, Bergeron, & Schwartz, 2005) were investigated using two independent online samples of Irish men (ns=241 and 253, respectively). Exploratory factor analyses suggested that a 15-item, 3-factor solution representing men's attitudes toward their body fat, muscularity, and height best described the data. The internal consistency and construct validity of scores on the Revised Male Body Attitudes Scale suggest that this measure holds promise as an indicant of men's attitudes toward their physical appearance. Limitations and strengths associated with the current research are discussed and directions for future research are outlined.     

Psychometric properties of the Muscle Appearance Satisfaction Scale among Irish and British men

The psychometric soundness of the Muscle Appearance Satisfaction Scale (MASS; Mayville, Williamson, White, Netemeyer, & Drab, 2002), a measure of muscle dysmorphia symptoms, was investigated using two independent online samples of Irish and British men (ns = 307 and 306, respectively). Exploratory and confirmatory factor analyses showed that, compared to the original 5-component solution for the 19-item MASS, a 6-item unidimensional version offered better fit to the data. Findings further upheld the internal consistency reliability, construct validity (e.g., via its associations with internalization of the muscular ideal and physical appearance comparisons), and discriminant validity (e.g., via its nonsignificant relationship with social desirability) of the MASS's scores. The limitations associated with the current research are discussed and directions for future research are articulated.     

Age-related differences in postural reaction time and coordination during voluntary sway movements

The elderly are known to exhibit declines in postural control during standing and walking, however little is known about how the elderly react under time-critical and challenging postural situations. The purpose of this study was to examine age-related differences in reaction time (RT) and the pattern of temporal coordination between center of pressure (COP), trunk and head motion during voluntary postural sway movements. Healthy young (n=10; mean=24 years; SD=5 years) and elderly men (n=8; mean=75 years; SD=2 years) stood on a force plate with tri-axial accelerometers attached to the head and lower trunk. Participants were required to generate sway in the anterior-posterior (AP) or medial-lateral (ML) direction in response to an auditory cue during two different testing conditions called Static reaction and Dynamic reaction. Static reactions involved the initiation of voluntary sway in either the AP or ML direction from quiet stance. Dynamic reactions involved an orthogonal switch of voluntary sway between the AP and ML directions. Compared to the young, elderly individuals exhibited slower RT during both Static and Dynamic reaction, and smaller differences in RT and phasing between COP, trunk, and head motion. The results of this study suggest that the elderly adopted more rigid coordination strategies compared to the young when executing a rapid change in direction of whole body motion. The rigid movement strategy of the elderly was presumably generated in an effort to compensate for increased challenge to the maintenance of stability.     

An inductive exploration of the social effectiveness construct space

ABSTRACT There is no agreement regarding the nature or number of dimensions that make up the social effectiveness domain. We inductively explore the relationships between a set of social effectiveness measures with the intention of identifying an initial set of dimensions. An exploratory factor analysis of the Social Competence Inventory (SCI, Schneider, 2001 ) resulted in the identification of four factors: Social Potency, Social Appropriateness, Social Emotional Expression, and Social Reputation. A joint factor analysis between the SCI and a set of extant measures resulted in the identification of the same four factors. A fifth factor emerged when a set of scales from an emotional intelligence measure was included in the analysis, suggesting that emotional intelligence is not captured within the common factor space defined by measures of social effectiveness. This study represents a first step in the establishment of a set of common social effectiveness dimensions.     

Performance on a face perception task is associated with empathy quotient scores, but not systemizing scores or participant sex

This preliminary study investigated whether individual differences in performance on a difficult social perception task (determining the sex of shape normalized, line drawn dynamic faces) are related to sex of observer, scores on an empathy quotient and scores on a systemizing quotient. Performance in the face perception task (N = 60) was above chance, indicating that participants could judge the sex of the degraded facial stimuli from dynamic information alone. There was a trend for women to be more accurate in their judgments of target sex than men, but regression analyses indicated that EQ scores alone predicted performance on the task. This study suggests that empathy may mediate sex differences in face perception abilities, and potentially other tasks in social perception.     

Metacognitive beliefs across the continuum of psychosis: comparisons between patients with psychotic disorders, patients at ultra-high risk and non-patients

BACKGROUND: Recent models of emotional disorders and psychosis implicate metacognitive beliefs in the development and maintenance of psychological distress. We predicted that patients with established psychotic disorders and those meeting at risk mental state (ARMS) criteria (and, thus, at increased risk of developing psychosis) would show higher levels of metacognitive beliefs than non-patient controls. Furthermore, we predicted that patients with psychosis would show higher levels of such beliefs than the at risk group. METHOD: The Metacognitions Questionnaire was administered to 73 patients with psychotic disorders, 43 ARMS patients and 188 non-patients. RESULTS: As predicted, patients with psychotic diagnoses and those at risk scored higher on metacognitive belief dimensions than non-patients. Patients with psychosis showed higher positive metacognitive beliefs than the at risk patients, indicating a greater range of unhelpful metacognitions overall, when compared to non-patients. CONCLUSIONS: These findings are consistent with metacognitive conceptualisations of psychological disorders. The implications of these findings for clinical practice are discussed.     

Stage-environment fit during adolescence: trajectories of family relations and adolescent outcomes

Within the framework of stage-environment fit theory, the authors examined the contribution of family relations to adolescent outcomes concurrently and longitudinally, as well as the moderating effects of gender and ethnicity in these associations. Data came from a longitudinal study of European American and African American families from a range of socioeconomic backgrounds. Results demonstrated that gender and ethnicity influenced both the level and rate of change in family relations and adolescent outcomes. Family relations contributed either concurrently or longitudinally to at least 1 of the adolescent outcomes. The effects of gender and ethnic moderation differed according to both the time frame and the outcome assessed.     

Women report being more likely than men to model their relationships after what they have seen on TV.

Students (21 men and 50 women) anonymously answered questions about imitating relationships seen on TV. The women were more likely than men to report trying to model family life after what they saw on TV situational comedies and to expect their significant other to act as those seen on TV. They also more frequently reported experiencing a significant other acting as those on TV. There was no difference by sex in current age, parents' marital status during the students' formative years, or age of separation, divorce, or widowing if any occurred. For neither women nor men did a broken home during the formative years correlate with looking to TV for information on relationships.
