Parental Support and Adolescent Motivation for Dieting: The Self-Determination Theory Perspective

This article focuses on parents’ role in overweight adolescents’ motivation to diet and successful weight loss. The study employed Self-Determination Theory (SDT) as the theoretical framework (Deci & Ryan, 2000, 2011). Ninety-nine participants (ages 20–30) who had been overweight during adolescence according to their Body Mass Index (BMI mean = 25, SD = 1.6), completed retrospective questionnaires about their motivation to diet and their parents’ behavior in the context of dieting. Findings from a structural equation modeling analysis suggested that participants who viewed their parents’ as more need-supportive demonstrated more autonomous motivation to diet, which, in turn, contributed to their successful weight loss. The findings highlight the importance of parental support of adolescents’ psychological needs in the quality of their motivation to diet. This is an important insight for parents and professionals who aim to encourage more constructive parent involvement in adolescents’ dieting and well-being.     

Subjective Well-Being in Adolescence: The Role of Self-Control,Social Support,Age, Gender,and Familial Crisis

Focusing on adolescents’ subjective well-being, the present study comprised three parts. The first examined the role of two coping mechanisms, self-control and social support, in predicting subjective well-being. The second related to the role of age and gender in predicting adolescents’ subjective well-being. The third raised the question of whether exposure to familial crisis would predict adolescents’ subjective well-being and whether self-control and social support would moderate the link between crisis and adolescents’ subjective well-being. Participants included 380 adolescents ages 13–17 years (M = 15.32, SD = .98; 194 boys, 176 girls, 10 unspecified), from six integrative junior-high and high schools in central Israel. All schools served a heterogeneous Jewish student population. Based on responses to a questionnaire identifying adolescents who reported experiencing a severe life crisis during the last year (e.g., severe illness in family, parent death or separation/divorce), the sample was divided into two groups: exposure to familial crisis (n = 96) and no exposure to familial crisis (n = 284). Outcomes revealed that both self-control and social support predicted adolescents’ subjective well-being. As expected, older adolescents presented lower levels of subjective well-being than younger ones. In contrast to the hypothesis, gender did not predict subjective well-being. Although exposure to crisis did not predict higher negative affect or lower positive affect, an interaction emerged between self-control and crisis in predicting positive affect. Thus, among adolescents who experienced crisis, better self-control skills predicted higher levels of positive affect.     

Exploring the Relationship Between Interrater Correlations and Validity of Peer Ratings

A field study was conducted to investigate the relationship between interrater correlations and validity estimates of peer ratings. Validity coefficients and interrater correlations were calculated for 281 work units in a large law enforcement organization in Israel. The main result was a weak positive linear relationship between these two variables. Furthermore, in some of the analyses conducted, a nonlinear quadratic component in the relationship between these measures was evident. Validity was low only when interrater correlation was very low (r = .4 and less). Above this level, validity was stable and almost did not change as interrater correlation increased. This finding, together with other studies (Borman, 1975 Borman, W. C. 1975. Effects of instructions to avoid halo error on reliability and validity of performance evaluation ratings. Journal of Applied Psychology, 60: 556–560. [Crossref], [Web of Science ®] , [Google Scholar]; Buckner, 1959 Buckner, D. N. 1959. The predictability of ratings as a function of interrater agreement. Journal of Applied Psychology, 43: 60–64.  [Google Scholar]; Freeberg, 1969 Freeberg, N. E. 1969. Relevance of rater-ratee acquaintance in the validity and reliability of ratings. Journal of Applied Psychology, 53: 518–524.  [Google Scholar]; Weekley & Gier, 1989 Weekley, J. A. and Gier, J. A. 1989. Ceilings in the reliability and validity of performance ratings: The case of expert raters. Academy of Management Review, 32: 213–222.  [Google Scholar]), cast doubt on the assertion that interrater correlation in the field of performance rating is a proper measurement of reliability.     

The factor structure of the Social Axioms Survey II (SASII) in the South African context

The objective of this study was to validate the new Social Axioms Survey II (SASII). The study sample comprised university students (n = 793) as well as their family members and friends (n = 645). Confirmatory factor analysis (CFA) following an initial exploratory factor analysis yielded a five-factor model: social cynicism, social complexity, reward for application, religiosity, and fate control. The findings of this study support the use of the new SASII in South Africa for research purposes.     

Employee Attributions of Corporate Social Responsibility as Substantive or Symbolic: Validation of a Measure

Using three samples aggregating over 1,000 working adults, we developed and tested a measure of Substantive and Symbolic Corporate Social Responsibility (CSR‐SS). The resultant 14‐item CSR‐SS scale is a reliable and parsimonious measure that is best represented by two broad and distinctive factors—substantive and symbolic attributions of CSR. Our findings provide evidence of a solid nomological network and criterion validity, supporting predictions that when employees attribute CSR as substantive, greater benefits accrue to the individual and the organisation as a whole than when CSR is attributed as symbolic. This measure contributes a valid and reliable tool toward the advancement of micro CSR research on both negative and positive consequences of organisations’ CSR proclaimed initiatives.     

A group just like me: The moderating role of conservation values on social projection

We examined the moderating role of personal values on social projection. Study 1 was conducted prior to the 1999 Israeli elections among activists of the Center party, a newly established centrist party. The more importance activists attributed to conservation values (values that emphasize stability and certainty) the more they projected their political views to their party. Study 2 was conducted prior to the 2003 Israeli elections among students with varied attitudes toward the Kadima party, another newly established centrist party. Conservation values interacted with support for the Kadima party in their effect on social projection: The more importance participants attributed to conservation values, the more positive was the relationship between support for the party and social projection. In Study 3, we examined the role of conservation values in an experimental study in which participants were members of a virtual team: Raising the accessibility of conservation values resulted in higher levels of social projection. Taken together, findings indicate that emphasizing conservation values leads to greater social projection. Copyright © 2009 John Wiley & Sons, Ltd.     

Personal Value Priorities and National Identification

We examine relations of personal value priorities to identification with one's nation. We hypothesize that relations of values to identification depend on the motivations that can be attained by identifying with a nation. Study 1 confirmed the hypothesis that identification with one's nation correlates positively with conservation values and negatively with openness to change values in Israel and the USA. Moreover, values predicted identification with the nation above and beyond Right‐Wing Authoritarianism. Study 2 showed that increasing the salience of conservation values produced higher identification with Israel, whereas increasing the salience of openness to change values produced lower identification. Study 3 tested the hypothesis that when identification with a national group conflicts with social expectations it has different, even reversed relations with value priorities. We examined identification of recent immigrants to Israel. The more pressure immigrants felt to assimilate, the more positive the correlation of conservation values with identification with the country of residence (Israel) and the more negative the correlation of conservation values with identification with the country of origin (Russia). Taken together, the findings point to the utility of values in revealing the motivational functions of identification with a nation.     

The effects of an interactive cognitive task (ICT) in suppressing fatigue symptoms in driving

BackgroundProlonged drive on inter-urban, monotonous roads has the potential of causing a decrease in the general level of arousal leading to a state of underload and fatigue. This study examines the effectiveness of an interactive cognitive task (ICT) in delaying fatigue symptoms induced by underload conditions. The ICT is an auditory-motor task which is based on the basic principles of a knowledge game known as “Trivia”.MethodTen participants took part in two experimental sessions of 140 min drive in a fixed-base simulator. In a within-subject counterbalanced design one session consisted of driving without ICT and the other included ICT operation. In the ICT session the game was activated after 60 min of driving.ResultsWhen activated, the ICT increased physiological indicators of arousal, increased subjective feelings of alertness, and improved driving performance. The physiological and driving performance measures revealed that the ICT activation had an immediate but localized influence on arousal. Post-drive questionnaires showed that in the ICT condition, the participants’ level of motivation increased and their feelings of sleepiness decreased.ConclusionsEngaging in cognitive tasks can counteract the effects of underload and increases driving safety as long as they are active. However, additional research is necessary to determine the effects of long term use.     

Convergent and discriminant validity of three measures of stage of change

The University of Rhode Island Change Assessment (E. A. McConnaughy, J. O. Prochaska, & W. F. Velicer, 1983), the Stages of Change Readiness and Treatment Eagerness Scale (W. R. Miller & J. S. Tonigan, 1996), and the Readiness to Change Questionnaire (S. Rollnick, N. Heather, R. Gold, & W. Hall, 1992) are commonly used multidimensional measures of stage of change. The authors examined the convergent and discriminant validity of drug-use versions of these 3 measures through multitrait-multimethod analysis in a population of indigent, out-of-treatment drug users (N = 377). Agreement in stage-of-change assignment and the relationship between stage of change and drug-use behaviors were also examined. Confirmatory factor analysis suggests that the Stages of Change Readiness and Treatment Eagerness Scale may have questionable convergent validity with the University of Rhode Island Change Assessment and Readiness to Change Questionnaire. There was moderate agreement in stage assignment. Analysis of behavior did provide some support for the construct validity of the measures. The results suggest that these drug-use stage-of-change measures may not be equivalent.
