The Skin Picking Impact Scale: Factor structure,validity and development of a short version

In the present study, we examined the psychometric properties of the Skin Picking Impact Scale (SPIS; Keuthen, Deckersbach, Wilhelm et al., 2001), a 10 item self‐report questionnaire designed to assess the psychosocial impact of skin picking disorder (SPD). Participants were 650 individuals who met criteria for SPD in an online survey. Exploratory and confirmatory factor analyses demonstrated a unitary factor structure with high internal consistency (α = 0.94). Consequently, we constructed an abbreviated 4‐item version that retained good internal consistency (α = 0.87) and a robust factor structure. Both the short and the full versions demonstrated discriminant and convergent/concurrent validity. In conclusion, the findings indicate that both versions are psychometrically sound measures of SPD related psychosocial impact; however, some potential limitations of the full scale are discussed.     

Psychometric Properties of the Perceived Social Support from Family and Friends Scale: Data from an Adolescent Sample in Ghana

Several studies have found that perceived social support plays a crucial role in the psychological and physical wellbeing of young people. A number of instruments measuring perceived social support have been developed and validated, including the Perceived Social Support from Family and Friends subscales. The psychometric properties of the Perceived Social Support from Family and Friends subscales have been demonstrated in a range of samples, although not in Ghana. The purpose of this study is to investigate the psychometric properties of the Perceived Social Support from Family and Friends subscales in Ghanaian adolescents using data from a school-based survey (N?=?770; 14–21 years). Participants completed a self-report questionnaire containing the Perceived Social Support from Family and Friends subscales, the Adolescent Stress Questionnaire, and the 12-item General Health Questionnaire. An exploratory factor analysis in addition to simultaneous confirmatory factor analyses with structural equation modelling were performed to evaluate the factor structure and factorial validity of the subscales along with Cronbach’s α and intercorrelations. Three factors and two factors were extracted for the Friends and Family subscales respectively. While the unidimensional model of the friends subscale had a better fit with the data than the three-factor model, the two-factor model of the family subscale had a better fit than the unidimensional model, even though the unidimensional models of both subscales produced higher internal consistency coefficients. With respect to construct validity, the family subscale demonstrated some evidence of convergent and discriminant validity, but the friends subscale demonstrated some evidence of only discriminant validity, in terms of the association between social support and common mental illness and perceived stress. It appears that the Perceived Social Support subscales are useful instruments for assessing social support from family and friends and could therefore be used to further our understanding about the role of social support in stressful life events and psychological functioning of Ghanaian adolescents, although further research is required for the friends subscale.     

Predicting the Emergence of Community Psychology and Community Development in 91 Countries with Brief Case Studies of Chile and Ghana

Using a mixed‐method analysis, we propose and test a framework for predicting the international development of community psychology (CP) and community development (CD) as two examples of applied community‐based research (CBR) disciplines aiming to link local knowledge generation with social change. Multiple regressions on an international sample of 91 countries were used to determine the relative influences of preexisting grassroots activism, population size, social and economic development, and civil liberties on estimates of the current strength of CP and CD based on Internet search and review of training courses and programs, published articles and journals, and professional organizations and conferences in these countries. Our results provide support for the proposed model and suggest that grassroots activism positively accounts for the development of CP and CD, above and beyond the influences of the other predictors. Brief qualitative case‐study analyses of Chile (high CP, low CD) and Ghana (high CD, low CP) explore the limitations of our quantitative model and the importance of considering other historical, sociopolitical, cultural, and geographic factors for explaining the development of CP, CD, and other applied community studies.     

Sense of Community, Neighboring, and Social Capital as Predictors of Local Political Participation in China

This study examines the state of sense of community, neighboring behavior, and social capital in the People’s Republic of China, and explores their ability to predict local political participation, in the form of voting in elections for Urban Resident/Rural Villager Committees. Using a nationally representative survey, rural, older and married residents and those with a primary or high school education and higher perceived socio-economic status are more likely to participate. In rural areas, men are more likely than women to vote. For urban residents, knowing one’s neighbors is more important whereas in rural areas, neighboring behavior is more important, but both predict voting. Social capital does not generally predict Chinese people’s local political participation. Western definitions of social capital derived from theories about networking, bonding and bridging ties may be too culturally individualistic for China, whose collectivist society and agrarian kinship networks predate Communism. Simply knowing and helping one’s neighbors, rather than more abstract notions of trust, reciprocity or membership, may lead to the development of local democracy.     

Peer Influence and Nonsuicidal Self Injury: Longitudinal Results in Community and Clinically-Referred Adolescent Samples

Research suggests that adolescents’ engagement in nonsuicidal self-injurious (NSSI) behaviors may be increasing over time, yet little is known regarding distal longitudinal factors that may promote engagement in these behaviors. Data from two longitudinal studies are presented to examine whether NSSI may be associated with peer influence processes. Study 1 included 377 adolescents from a community-based sample; Study 2 included 140 clinically-referred adolescents recruited from a psychiatric inpatient facility. In Study 1, adolescents’ NSSI was examined at baseline and one year later. Adolescents’ nominated best friend reported their own levels of NSSI. In Study 2, adolescents’ NSSI was examined at baseline as well as 9 and 18-months post-baseline. Adolescents’ perceptions of their friends’ engagement in self-injurious behavior (including suicidality) and depressed mood also were examined at all three time points. Baseline depressive symptoms were measured in both studies; gender and age were examined as moderators of peer influence effects. Results from both studies supported longitudinal peer socialization effects of friends’ self-injurious behavior on adolescents’ own NSSI for girls, but not for boys, even after controlling for depressive symptoms as a predictor. Study 1 suggested socialization effects mostly for younger youth. Results from Study 2 also suggested longitudinal socialization effects, as well as peer selection effects; adolescents’ NSSI was associated with increasing perceptions of their friends’ engagement in depressive/self-injurious thoughts and behavior. Findings contribute to the nascent literature on longitudinal predictors of NSSI and to work on peer influence.     

Health Anxiety: Latent Structure and Associations with Anxiety-related Psychological Processes in a Student Sample

Although currently classified as a somatoform disorder, cognitive-behavioral models conceptualize hypochondriasis (HC) as a severe form of health anxiety. The Short Health Anxiety Inventory (SHAI) is a measure derived from this conceptualization that measures health anxiety symptoms across the range of severity. Previous studies have reported inconsistent findings regarding this measure’s factor structure, but these studies employed factor analytic tools that did not account for the categorical nature of SHAI items. The present psychometric study was designed to address these inconsistencies using categorical factor analysis. Using data from a large student sample we found that the SHAI had two factors: Illness Likelihood and Illness Severity. We also examined the relationship between these domains and cognitive variables associated with other anxiety disorders. Results suggested that the psychological processes present in obsessive-compulsive disorder and panic disorder are also associated with health anxiety. Implications for the conceptualization and classification of severe health anxiety are discussed.     

Biological components of colour preference in infancy

Adult colour preference has been summarized quantitatively in terms of weights on the two fundamental neural processes that underlie early colour encoding: the S−(L+M) (‘blue–yellow’) and L−M (‘red–green’) cone‐opponent contrast channels ( Ling, Hurlbert & Robinson, 2006 ; Hurlbert & Ling, 2007 ). Here, we investigate whether colour preference in 4–5‐month‐olds may be analysed in the same way. We recorded infants’ eye‐movements in response to pairwise presentations of eight colour stimuli varying only in hue. Infants looked longest at reddish and shortest at greenish hues. Analyses revealed that the L−M and S−(L+M) contrast between stimulus colour and background explained around half of the variation in infant preference across the hue spectrum. Unlike adult colour preference patterns, there was no evidence for sex differences in the weights on either of the cone‐opponent contrast components. The findings provide a quantitative model of infant colour preference that summarizes variation in infant preference across hues.     

Maternal depression: A review of relevant treatment approaches for mothers and infants

The negative impact of postpartum depression on the mother‐infant relationship and infant development more generally has been well documented. Compared to infants of nondepressed mothers, infants of depressed mothers have been shown to be less securely attached to their caregivers and often have cognitive, emotional, and behavioral deficits that persist well into childhood. Recent evidence has suggested that reduction of maternal depressive symptoms may itself not be sufficient to prevent negative effects on children. Rather, treatments that target the mother‐infant relationship may have great potential in providing a buffer against the potentially damaging effects of postpartum depression. Based on our review of several treatment‐outcome studies, we conclude that mother‐infant psychotherapies and home‐based interventions are generally efficacious in their goal of ameliorating detrimental consequences for children of depressed mothers. Nonetheless, the field must continue to investigate the extent to which treatment gains are maintained over time and the mechanisms by which protective effects occur. It is likely that the most efficacious treatment approaches will be those that address the needs of the mother, the infant, and their relationship.
