This study investigates the equivalent factorial structure of the Brief Symptom Inventory (BSI) in clinical and nonclinical Jordanian populations, using both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The 53-item checklist was administered to 647 nonclinical participants and 315 clinical participants. Eight factors emerged from the exploratory factor analysis (EFA) for the nonclinical sample, and six factors emerged for the clinical sample. When tested by parallel analysis (PA) and confirmatory factor analysis (CFA), the results reflected a unidimensional factorial structure in both samples. Furthermore, multigroup CFA showed invariance between clinical and nonclinical unidimensional models, which lends further support to the evidence of the unidimensionality of the BSI. The study suggests that the BSI is a potentially useful measure of general psychological distress in clinical and nonclinical population. Ideas for further research are recommended.

Theories of social collapse are not only the views that characterize ?societies deep in crisis?, but rather an expression of lack of belief in prosperity and central importance of the civilization in which we live. These theories follow processes of degradation of human societies, the decline of civilization`s powers and the loss of its cultural values resulting in their complete disappearance. This paper defines the subject of study and provides an overview of the history of these theories and their contemporary types by taking the main causes of collapse criteria as the basis for theory building. After the review of contemporary multi-factor analysis of collapse, mainly within the science of complex systems, full attention is focused on two atypical, yet very productive, contemporary theories of social collapse that are elaborated in detail: Jared Diamond`s theory, which studies social collapses by observing relations of other variables that can lead to collapse with environmental problems as central; and Peter Turchin`s theory which, revitalizing with modern scientific achievements Ibn Khaldun`s classical theory of ?asabia? (group feeling, spirit of community), sees social collapses as a consequence of the decline of cohesion provided by asabia. The final part of the work gives a critical review of these two theories and their relation with classical theories of social collapse (primarily those of Arnold Toynbee) and points to their mutual productive complementarity.

Development And Validation

The main goal of our research was to develop a new measure of persistence and to assess its construct validity and psychometric proprieties. First, we discuss the history of the psychological construct of persistence, defined here as the tendency to remain engaged in specific goal-related activities, despite difficulties, obstacles, fatigue, prolonged frustration or low perceived feasibility. The developed scale, measuring motivational persistence, contains three-factors: long-term purposes pursuing, current purposes pursuing and recurrence of unattained purposes. The results of the two validation studies conducted, employing both exploratory and confirmatory factor analysis, advocate the hypothesized structure. Also, the Pearson and canonical correlations between the three factors of the new self-report scale and other three related measures (and their factors) indicate good levels of convergent and divergent validity of the new scale.

Abstract Objective Self-report scales are commonly used to evaluate non-specific symptoms following concussion. While several scales have been developed, few were created using a systematic process and most contain several ambiguous items that may be misinterpreted. To address this, a new theoretically-based, multidimensional measure was designed to assess Cognitive, Neuropsychiatric, and Somatic symptoms associated with concussion. This study used sophisticated psychometric techniques to develop the Texas Postconcussion Symptom Inventory (TPSI) and establish initial reliability and validity. Method Because concussion symptoms are non-specific, a pool of 76 potential items was developed and administered to a diverse clinical sample (N = 350) that included patients with concussion, epilepsy, and dementia. Polychoric correlations were utilized to remove items based on poor fit/multicollinearity and an exploratory factor analysis (EFA) with an Oblimin rotation was used to determine factor structure. Results A three-factor model best fit the data, and represented Cognitive, Neuropsychiatric, and Somatic domains as designed. Ten items were discarded, resulting in a total of 66 items. The model explained 48.5% of the total variance and contained adequate sampling (Kaiser-Meyer-Olkin measure =0.92) and sufficient item correlations (Bartlett’s Test of Sphericity, p < 0.05) for EFA. All three factor structures displayed high internal consistency (Cronbach’s α > 0.88). Conclusions The TPSI is a brief, multidimensional measure with evidence of strong internal consistency and reliability as well as distinct Cognitive, Neuropsychiatric, and Somatic symptoms associated with concussion. Future research will investigate its convergent and divergent validity in concussion as compared to existing popular symptom measures.

While it is usual among psychiatrists to express dissatisfaction with psychiatric classification and its problems it is by no means unusual for their psychological colleagues to advocate factor analysis as an effective technique for resolving such problems. For example, Burt (1954) describes factor analysis as “essentially a statistical device for securing the best available scheme of classification”. Yet the problems and the device tend to remain apart, the former becoming intensified, the latter undergoing continued improvements. Twenty-five years ago T. V. Moore (1930) demonstrated that the application of factor analysis to the study of psychiatric disorders was feasible, and more recent work, especially that of Eysenck (e.g. 1947) has impressively shown its fruitfulness. That some clinicians remain sceptical of the claims made for these techniques is, in part, due to the infrequency with which factorial studies bearing on psychiatry have been pursued far enough for their implications to be tested and the findings integrated with those established by other scientific methods. This deficiency may be attributable to the fact that large scale programme research (Eysenck, 1953) is an almost essential condition, if this is to be achieved.
