Perceived collective efficacy to stop aggression at school: A validation of an Italian and a Swedish version of a scale for adolescents

Collective efficacy to stop peer aggression in the school context refers to adolescents’ beliefs about the capability of students and teachers in their school to work together to counteract aggressive behaviours among peers. This study presents the Italian and Swedish versions of a recently developed scale to measure the construct. Factorial structure and measurement invariance of the scale were assessed in two samples of adolescents aged 10–15 years. The findings support both a two-dimensional and a three-dimensional scale across gender and countries, demonstrating the importance of making distinctions between different forms of aggression when measuring collective efficacy to stop aggression. A one-dimensional scale was only supported in the Swedish sample. The results support the use of the Collective Efficacy to Stop Aggression scale with both Italian and Swedish adolescents.     

Examining the cross‐cultural validity of the positive affect and negative affect schedule between an Asian (Singaporean) sample and a Western (American) sample

The positive affect and negative affect schedule (PANAS) is a popular measure of positive (PA) and negative affectivity (NA). Developed and validated in Western contexts, the 20‐item scale has been frequently administered on respondents from Asian countries with the assumption of cross‐cultural measurement invariance. We examine this assumption via a rigorous multigroup confirmatory factor analysis, which allows us to assess between‐group differences in both strength of scale item‐to‐latent factor relationship (metric invariance test) and mean of each scale item (scalar invariance test), on a large sample of 1,065 respondents recruited from Singapore (Asian sample) and the United States (Western sample). We found that two items assessing PA (“excited” and “proud”) and three items assessing NA (“guilty,” “hostile,” and “ashamed”) exhibited metric noninvariance whereas 11 of the remaining metric invariant items exhibited scalar noninvariance, suggesting that the PA and NA constructs differ from what the PANAS is expected to measure for Asian respondents. Our findings serve as a cautionary note to researchers who intend to administer the PANAS in future studies as well as to researchers interpreting the results of past studies involving respondents from Asian countries.     

Factorial Structure and Measurement Invariance of the Innovative Behavior Questionnaire

The article presents an analysis of the factorial structure and measurement invariance of the Innovative Behavior Questionnaire, developed by Scott and Bruce. Although the instrument is widely used to capture individuals' innovative behavior, very little evidence concerning its psychometric properties is available. A time‐lagged study among 382 employees was conducted to check the factorial structure of the questionnaire, using confirmatory factor analysis, as well as its measurement invariance across gender and time. One‐factor structure (with correlated error terms of first three items) and strict invariance across time and across gender of the Innovative Behavior Questionnaire were demonstrated. As such, the measure can be used as a reliable tool for capturing individuals' innovative behavior by self‐report.     

Evaluation of the Norwegian version of the Adolescent Stress Questionnaire (ASQ-N): factorial validity across samples

In spite of the potential significance of stressors, the past decades have yielded only limited and incremental progress in the field of the development of valid and reliable stress inventories for adolescents. The Adolescent Stress Questionnaire (ASQ-N) was developed to address the domain of stressors specific to adolescent experience. The present study reports an evaluation of factorial validity, as well as the construct validity of the Norwegian version of the Adolescent Stress Questionnaire (ASQ-N) across two samples, with the use of confirmatory factor analysis (CFA). Gender and age differences on the ASQ-N sub-dimensions are also evaluated. The CFA supported a seven-factor structure, where all sub-dimensions showed adequate internal consistency. The sub-dimensions were correlated positively with measures of depression and anxiety, and were correlated negatively with self-esteem, supporting the construct validity of the ASQ-N. Significant gender differences in self-reported adolescent stress were found in five of the seven scales, where girls had higher mean scores than boys. The correlation between each stress scale and age was weak, with significant correlations found in four of the seven scales. It is suggested that the ASQ-N is a measure of adolescent stress that is adequate for the research context, as well as for clinical investigation.     

Adolescent stress: Evaluation of the factor structure of the Adolescent Stress Questionnaire (ASQ‐N)

Moksnes, U. K., Byrne, D. G., Mazanov, J. & Espnes, G. A. (2010). Adolescent stress: Evaluation of the factor structure of the Adolescent Stress Questionnaire (ASQ‐N). Scandinavian Journal of Psychology, 51, 203–209. The present study reports an evaluation of the factor structure of the Norwegian version of the Adolescent Stress Questionnaire (ASQ‐N) among 723 students. Principal components analysis (PCA) revealed nine internally consistent dimensions of adolescent stress. Scales constructed from this PCA correlated positively with measures of depression and anxiety and negatively with self‐esteem. Girls reported higher stress levels than boys in seven of the nine scales and age was also positively correlated with the scale scores of adolescent stress. The results revealed that the instrument has potential for measuring adolescent stress. The stability of the ASQ‐N needs to be tested repeatedly, across cohorts and over time, to establish the adequacy for use in Norwegian adolescent studies.     

The Perceived Stress Scale: Factor structure and relation to depression symptoms in a psychiatric sample

The present study sought to examine the factor structure and psychometric properties of the Perceived Stress Scale (PSS) when administered to psychiatric patients. We also examined predictive validity of the PSS by assessing the association between the Perceived Stress Scale and the Beck Depression Inventory. A heterogeneous sample of 96 psychiatric patients (48 men, 48 women) completed the Perceived Stress Scale (PSS) and the Beck Depression Inventory. Factor analysis of the PSS established that the scale consisted of two factors. The first factor was comprised primarily of items reflecting adaptational symptoms. In contrast, the second factor consisted of items reflecting coping ability. Both factors had an adequate degree of internal consistency. Finally, a series of regression analyses predicting depression found that both factors accounted for unique variance in depression scores in women, but only the first factor accounted for unique variance in men. It is concluded that the PSS is a multidimensional and internally consistent measure of perceived stress.This research was supported by Grant 410-91-1690 from the social sciences and Humanities Research Council of Canada as well as by grants from the Research and Program Evaluation Committee Brockville Psychiatric Hospital.     

The Prospective and Retrospective Memory Questionnaire (PRMQ): factorial structure, relations to global subjective memory ratings, and Swedish norms

The factorial structure of the Prospective and Retrospective Memory Questionnaire (PRMQ; Smith et al., 2000) was examined in a Swedish population based sample (N= 540, age range; 35-90 years). Concurrent validity was assessed by relating PRMQ to global ratings of memory. Confirmatory factor analyses of the PRMQ items indicated a superior fit of a three-factor model, with prospective and retrospective memory as orthogonal factors and episodic memory as a common factor. Furthermore, the PRMQ scales correlated with the global ratings of memory, suggesting that each rating contributed with unique variance in predicting PRMQ scores. Given differences in levels of complaints as compared with prior research (Crawford et al., 2003) norms for the Swedish version are provided. In conclusion, the present findings extend earlier work by providing additional support for the construct and concurrent validity of the PRMQ scales.     

The reliability and validity of the Perceived Stigmatization Questionnaire (PSQ) and the Social Comfort Questionnaire (SCQ) among an adult burn survivor sample

In this study, 361 adult burn survivors completed the Perceived Stigmatization Questionnaire (PSQ), the Social Comfort Questionnaire (SCQ), and other measures. Both the PSQ and SCQ had good internal consistency indices. Factor analysis of the PSQ yielded 3 factors (absence of friendly behavior, confused/staring behavior, and hostile behavior). The SCQ had 1 factor. Conjoint factor analysis with measures of related constructs (body esteem, body-esteem importance, depression, social support) suggested that PSQ and SCQ measure distinct constructs. Correlations with the related psychosocial constructs and burn characteristics suggested the PSQ and SCQ have good convergent and discriminant validity. Limitations of the study are discussed.     

Factorial structure of the perceived stress scale and implications for scoring

IntroductionThe 10-item Perceived Stress Scale (PSS-10) is a brief, widely-used measure of perceived stressful experiences that evaluates the degree to which people perceive their lives as unpredictable, uncontrollable or overloaded.ObjectiveThe present study examined the factor structure of the Greek version of the PSS-10.MethodUsing a representative sample of 320 adults from Cyprus, alternative confirmatory factor analytic models were compared to specifically assess bidimensional versus unidimensional specifications for the scale.ResultsA bifactor model with a general factor which loads on all items and a specific one which loads on positively-worded items that capture the notion of self-efficacy to deal with stressful situations, was found to fit well to the data, while providing evidence of a robust latent factor of general distress. Reliability and construct validity evidence with multiple criterion variables were also examined.ConclusionsAlthough a simple unidimensional specification has not been empirically supported in previous research, bifactor modeling exemplifies the extent of multidimensionality and implies that a single score may be reliably used for practical purposes.     

The structure of adversarial growth in a sample of cancer patients 8 years post-diagnosis: a revision of the SLQ-38

Stressful and traumatic events may trigger positive life changes, so-called adversarial growth. Despite growing interest in this topic, the structure and dimensionality of this concept has not been established. Recently, empirical reviews have suggested that the factors underlying this construct are highly related. Currently, the use of confirmatory factor analysis to test this hypothesis is advocated. Using data from cancer patients (n = 206), this study investigated the dimensionality of a Dutch translated version of the Silver Lining Questionnaire (SLQ-38). A 16-item SLQ (SLQ-16), with three subscales or first-order factors (enhanced personal relationships, changes in life philosophy and changes within the self) loading on a second-order general adversarial growth factor, was a good fitting model. In conclusion, the SLQ-16 may prove useful in the assessment of adversarial growth following illness.     

Factorial structure of the ‘ToM Storybooks’: A test evaluating multiple components of Theory of Mind

This study examined the factorial structure of the Theory of Mind (ToM) Storybooks, a comprehensive 93‐item instrument tapping the five components in Wellman's model of ToM (emotion recognition, understanding of desire and beliefs, ability to distinguish between physical and mental entities, and awareness of the link between perception and knowledge). A sample of 681 three‐ to eight‐year‐old Italian children was divided into three age groups to assess whether factorial structure varied across different age ranges. Partial credit model analysis was applied to the data, leading to the empirical identification of 23 composite variables aggregating the ToM Storybooks items. Confirmatory factor analysis was then conducted on the composite variables, providing support for the theoretical model. There were partial differences in the specific composite variables making up the dimensions for each of the three age groups. A single test evaluating distinct dimensions of ToM is a valuable resource for clinical practice which may be used to define differential profiles for specific populations.     

A Swedish translation of the 20-item Toronto Alexithymia Scale: cross-validation of the factor structure

The purpose of this study was to develop a new Swedish translation of the twenty-item Toronto Alexithymia Scale (TAS-20) and to examine if the theoretical structure that underlies the factor structure of the English version of the TAS-20 could be recovered in this Swedish translation of the instrument. A sample of 157 undergraduate students of psychology was tested. Using confirmatory factor analysis, the previously established three-factor TAS-20 model was found to be replicable in this sample. In addition, the Swedish translation of the TAS-20 showed adequate internal reliability. The present study also illustrates the importance of using back translation methodology when transposing psychometric instruments from one language to another.     

Factor structure of the Perceived Stress Scale (PSS) in a sample from Mexico

The aim of this study was to analyze the cultural adaptation of the European Spanish version of the Perceived Stress Scale (PSS; Cohen, Kamarak, & Mermelstein, 1983), for its use in Mexican samples. Using a random sample of students, internal consistency was analyzed and the factor structure of the Spanish version of the PSS was compared with the factor structure found in the English version. Internal consistency was adequate (alpha = .83) and confirmatory factor analysis corroborated the factor structure. Factor 1 explained 42.8% of the variance and Factor 2 accounted for 53.2%. The goodness-of-fit measures also revealed an adequate fit. The cultural adaptation of the PSS was also evaluated with satisfactory results.     

Perceived causes of everyday memory problems in a population‐based sample aged 39–99

There is usually a weak relation between memory complaints and laboratory memory performance, but few studies have investigated what people perceive as causes of their everyday memory problems. This study investigated prevalence, severity and perceived causes of memory problems in a population‐based sample (N = 361, age‐range 39–99). 30.2 per cent of the participants reported memory complaints (at least moderate memory problems). Higher age was associated with more severe memory problems, but the age‐related differences were small. The most frequent perceived causes were age/ageing, stress and multitasking. Age/ageing as a cause was more frequent among older participants, and stress and multitasking were more frequent among middle‐aged participants. The results suggest that everyday stress and level of engagement in multiple tasks or commitments, that place demands on cognitive resources, are important variables to consider when studying the relations between subjective everyday memory measures, age and memory performance in the laboratory.

Reliability,Validity and Invariance of the Narcissistic Personality Questionnaire for Children-Revised (NPQC-R)

Using confirmatory factor analysis, this study compared the 4-factor 18-item Narcissistic Personality Questionnaire for Children (NPQC) and the 2-factor, 12-item Narcissistic Personality Questionnaire for Children-Revised (NPQC-R). Support was found for the 2-factor structure of the 12-item NPQC-R using two independent adolescent school-based samples (n = 479 and n = 470). The 2-factor NPQC-R model (i.e., Superiority, Exploitativeness) showed a better fit in both adolescent samples than the alternative 4-factor NPQC model. There was strong support for NPQC-R’s invariance across gender and age. The NPQC-R was found to have reasonable internal consistency estimates, test–retest reliability estimates, and adequate convergent and discriminant validity estimates. Collectively, these results support the utility of the NPQC-R as a measure of narcissism in children and adolescents. A copy of the NPQC-R and scoring key can be obtained from Rebecca P. Ang.     

Assessment of self-conscious emotions: a Swedish psychometric and structure evaluation of the Test of Self-Conscious Affect (TOSCA)

The Test of Self-Conscious Affect (TOSCA) is a well-established scenario-based questionnaire assessing self-conscious emotions, such as shame and guilt, which have been shown to be differentially associated with a variety of functional, motivational, behavioral and health outcomes. The aim of this study was to evaluate the psychometric properties and internal structure of a Swedish version of TOSCA in a sample of 361 healthy adults. The psychometric properties and internal consistency of the Swedish version were at level with the original US TOSCA version for shame, guilt and detachment. The internal structure of the Swedish version was acceptable for shame, guilt and detachment but contained shortcomings in assessment of externalization.     

Perceived Stress in Young Carers: Development of a Measure

We report the development of a 5-factor, 31-item, Young Carers Perceived Stress Scale (YCPSS) from an initial 50-item pool. The scale was developed and tested on 108 young carers aged between 12–18 years, and acceptable Cronbach Alpha values were obtained for the individual factors and the overall scale. In addition, both the overall scale and individual factors produced a pattern of correlations with social support, burden of care, psychological distress, and coping, supporting the initial validity and utility of the scale.     

Cross‐cultural validation of the factor structure for the Korean version of the Classroom Climate Inventory

The purpose of the present study was to validate the Classroom Climate Inventory (CCI) in Korean middle schools. Specifically, we investigated whether the original eight‐factor structure of the Japanese version of the CCI (Involvement, Affiliation, Friction, Satisfaction, Self‐disclosure, Task Orientation, Order, and Equity) is appropriate for Korean middle schools. The results indicated that the Korean version of the CCI showed a different factor structure from the Japanese CCI. In the cross‐culturally validated CCI, the Friction factor included in the Japanese version was divided into two factors (i.e., Harmony and Conflict), and Equity was excluded. The final model of the Korean CCI displayed acceptable goodness‐of‐fit indices, which indicated that it is a valid instrument by which to measure the classroom climate of Korean middle schools. Lastly, implications for future research and limitations are discussed.     

Parents' description of conduct problems in their children - a test of the Eyberg Child Behavior Inventory (ECBI) in a Swedish sample aged 3-10

The Eyberg Child Behavior Inventory (ECBI) is a widely used 36-item uni-dimensional parent rating scale constructed to measure disruptive behavior problems in children. However, in an American sample a 22-item version, including three subscales, has been suggested in order to increase the usefulness of the ECBI. Two studies were conducted to test the ECBI in a Swedish sample (N = 841). The aims of Study I were (a) examine the psychometric properties of the ECBI (b) to investigate the correspondence between mothers' and fathers' ratings, and (c) to obtain Swedish norms. The aim of Study II was to test the suggested three-factor solution in the Swedish sample using a confirmatory factor analysis (CFA). The ECBI showed good psychometric properties also in the present study, and Swedish normative data is presented. The best-fitting CFA-model was identical to the previously suggested three-factor model, which thus might be a useful alternative to the 36-item version.     

Measuring illness representations in breast cancer survivors (BCS) prescribed tamoxifen: Modification and validation of the Revised Illness Perceptions Questionnaire (IPQ-BCS)

Objective: The Revised Illness Perceptions Questionnaire (IPQ-R), widely used to assess illness perceptions, may fail to measure unique characteristics of different illnesses. This study modified and validated the IPQ-R for breast cancer survivors to provide detailed understanding of the specific illness perceptions held by these patients.

Design: Initial modifications were made following qualitative interviews and were revised in a think-aloud study. The modified scale was tested in 753 breast cancer survivors prescribed tamoxifen. Modifications included adding a tamoxifen consequences scale and adapting the timeline scales to measure beliefs around risk of recurrence and cure. A confirmatory factor analysis was conducted on the modified questionnaire and an exploratory factor analysis on the causal beliefs scale. Test–retest reliability, internal consistency and construct validity were also examined.

Results: The proposed eight-factor structure showed acceptable model fit, with high loadings and good reliability for all subscales. Correlations between subscales were consistent with theory and previous research.

Conclusions: The IPQ-BCS is valid and reliable, and provides unique understanding of specific perceptions held by this population, including beliefs surrounding risk of recurrence and consequences of ongoing hormonal treatment. Identifying these perceptions will aid development of interventions targeting depression, fear of recurrence and medication non-adherence.
