AbstractObjective:Our aim was to develop and test a brief measure of generativity and ego-integrity that is suitable for use in palliative care settings.Method:Two measures of generativity and ego-integrity were modified and combined to create a new 11-item questionnaire, which was then administered to 143 adults. A principal-component analysis with oblique rotation was performed in order to identify underlying components that can best account for variation in the 11 questionnaire items.Results:The two-component solution was consistent with the items that, on conceptual grounds, were intended to comprise the two constructs assessed by the questionnaire.Significance of Results:Results suggest that the selected 11 items were good representatives of the larger scales from which they were selected, and they are expected to provide a useful means of measuring these concepts near the end of life.

This note extends the results in the 2016 article by Raykov, Marcoulides, and Li to the case of correlated errors in a set of observed measures subjected to principal component analysis. It is shown that when at least two measures are fallible, the probability is zero for any principal component—and in particular for the first principal component—to be error-free. In conjunction with the findings in Raykov et al., it is concluded that in practice no principal component can be perfectly reliable for a set of observed variables that are not all free of measurement error, whether or not their error terms correlate, and hence no principal component can practically be error-free.

The Stability

The Preschool Behaviour Questionnaire has been widely used in North-America to study social competencies and behavioural problems of preschool children. The 30 item rating scale was created by Behar and Stringfield (1974) as an adaptation of Rutter's (1967) Children's Behaviour Questionnaire intended for elementary school children. In their original study Behar and Stringfield proposed a three-component solution for their data: hostileaggressive, anxious-fearful, hyperactive-distractible. Most studies using the Behar Preschool Behaviour Questionnaire, (B-PBQ) have been using this three-component solution. Fowler and Park (1979), after a study of a "normal" population sample, concluded that a two-component solution (aggressive-hyperactive-distractible, anxious-fearful) was a better approximation to simple structure and more easily interpretable. They also concluded that the two-component solution was stable across sexes, but questioned the stability for "populations differing significantly in socioeconomic or ethnic composition". This study addresses the "simple structure" problem and the "stability of structure" problem for the B-PBQ. Four different samples ranging from N=383 to N=1161 were assessed in francophone schools in Montreal. Results of principal component analyses compared to Behar and Stringfield's data as well as Fowler and Park's data lead to the following conclusions: a two-principal-component solution has a simpler structure and is easier to interpret with reference to Rutter's Children's Behaviour Questionnaire; the two-component solution is stable across sexes, ages, socioeconomic populations and cultures. The Preschool Behaviour Questionnaire paired with the Children's Behaviour Questionnaire should be suitable for longitudinal and cross-cultural studies of social competencies from preschool to junior high school.

War And Conflict

Objectives: The primary aim of this research was to develop a questionnaire that assesses perceived injustice among survivors of war and trauma in conflict areas and to evaluate its psychometric properties. This paper presents the first preliminary validation. Furthermore, the assumption that the general perception of injustice correlates with one’s own experiences of injustice and violence was tested. Methods: The 24-item Perceived Injustice Questionnaire (PIQ) was administered partly online and partly in a paper–pencil version to 89 students of the University of Dohuk in Northern Iraq, an area that has been affected by crisis and war for many years. Principal component analysis was used for factor extraction and internal consistency was determined. The Mann–Whitney-U test was used to calculate the group differences between people with and without experience of physical violence and strong experiences of injustice because Kolmogorov–Smirnov tests showed that the data are not normally distributed. Results: Principal component analysis yielded a four-component solution with eigenvalues being the greater one. Cronbach’s alpha for each scale was acceptable to satisfactory. Significant results of the Mann–Whitney U tests supported our assumptions of between-group differences on each of the subscales (emotional and cognitive consequences, injustice perception, injustice experience, revenge, and forgiveness). Discussion: The findings of this study support the construct validity and the reliability of the PIQ. For this reason, it can be seen as a useful addition to the psychological assessment in psychotherapeutic settings of survivors of war and violence. In conclusion, and based on the PIQ, we suggest the development of a new set of therapy modules with worksheets, focusing on the perception, dealing, and understanding of feeling of injustice as an addition to the existing trauma therapy manual for therapy in war and conflict areas.

Aims: The primary aim of this study was to examine anxiety symptoms as measured by the Geriatric Anxiety Inventory (GAI) in older patients with depression, dementia, or psychotic disorders. The secondary aim was to conduct a principal component analysis (PCA) of the GAI and to examine whether its subscales differ between the 3 disorders. Methods: We included data from 428 patients who were admitted to a department of geriatric psychiatry and examined according to a standardized protocol. The GAI was used to measure current anxiety symptoms. Results: The GAI symptoms occurred more frequently in the group with depression than in the other 2 groups. The PCA of the GAI with oblimin rotation resulted in a 2-component solution, labelled as “worries” (explained variance 46.3%, Cronbach's α 0.92) and “physical symptoms” (explained variance 7.1%, Cronbach's α 0.85). Conclusion: The results indicate that in old age, anxiety is especially prevalent in depression. The 2-component solution indicates that the GAI measures 2 different aspects of anxiety with different symptomatology.

Background: The Functional Assessment of Chronic Illness Therapy-Palliative (FACIT-Pal) 14 instrument measures the quality of life in palliative care patients but its psychometric properties are not well characterized. Objectives: To establish the reliability and validity of the FACIT-Pal 14 in an outpatient palliative care clinic population. Methods: The FACIT-Pal 14 was administered to 227 patients in an outpatient palliative care clinic at a large, urban academic medical center. Internal consistency reliability was assessed with Crohnbach’s α, and principal component analysis was used to investigate for multiple underlying latent variables. Construct validity was tested by comparing mean scores in various subgroups. Results: The FACIT-Pal 14 has Crohnbach’s α of 0.76, which increases to 0.79 if 2 items are removed. Principal component analysis supports a single latent variable underlying the instrument. Significantly lower mean scores were found in patients with Eastern Cooperative Oncology Group (ECOG) functional status 3 to 4 compared with patients with ECOG functional status 1-2 ( P = .007), in patients with life expectancy under 6 months compared to those with 6 months or greater ( P = .003), and in patients referred to clinic for pain and symptom management compared with patients referred for other reasons ( P = .038). Instrument scores did not significantly differ between men and women or between white and nonwhite patients ( P = .525 and P = .263, respectively). Conclusions: In an outpatient palliative care clinic population, the FACIT-Pal 14 has good internal consistency, but removal of 2 items would improve consistency. One latent variable underlies the instrument and there is evidence of construct validity.

122 subjects served in a study which examined whether neuroticism, introversion, and sex predicted interest in reading psychological self-help paperbacks. Subjects completed (a) a pretest questionnaire asking about types of self-help books, (b) the Eysenck Personality Inventory, (c) a chapter from a bestselling self-help book, and (d) an 11-item questionnaire about their interests in self-help books, therapy, and psychological problems. A principal component analysis on 12 questions (dependent measure) gave two major factors, one dealing with self-help books the other with therapy. Scores on these two factors, for each subject, were entered in a regression analysis, using neuroticism, introversion and sex as predictors. Neuroticism was the only significant predictor.

Background: The main measure to generate utility data for economic evaluations is the EQ-5D, but no study has tested whether or how to map from palliative care measures to the EQ-5D. Aims: To assess the level of conceptual overlap between palliative outcomes and the EQ-5D, and the feasibility of mapping between them to obtain utilities for the Palliative care Outcome Scale. Design: A cross-sectional secondary analysis of data from three studies. Setting/participants: Patients receiving palliative care and bereaved relatives, recruited from three tertiary National Health Service hospitals in South London. Methods: The overlap between both measures was assessed using principal component analysis. The Palliative care Outcome Scale was mapped onto the EQ-5D using three regression models. Results: Spearman’s correlations between both instruments were low (mean rho = 0.11). The principal component analysis showed the Palliative care Outcome Scale is associated with only two EQ-5D dimensions (pain; and anxiety/depression). No Palliative care Outcome Scale items loaded onto the mobility, self-care and usual activities dimensions of the EQ-5D. The mapping models performed poorly at predicting utilities from Palliative care Outcome Scale data (mean absolute error >0.3 and R2 <0.10). Hence, none of the models can be recommended as acceptable for calculating utilities from Palliative care Outcome Scale responses. Conclusion: Differences between the Palliative care Outcome Scale and the EQ-5D do not undermine the qualities of either instrument when used for their own purposes. However, due to conceptual differences, the EQ-5D does not capture some of the concerns measured by the Palliative care Outcome Scale, and therefore, mapping onto the EQ-5D is unlikely to provide an appropriate basis for estimating utilities for conducting economic evaluations in palliative care studies.

Background: Sexual dysfunction is common in multiple sclerosis (MS) but reliable and valid measurement in this population is needed. Objective: The objective of this research is to re-validate the Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 in a large US sample. Methods: A total of 6300 MS patients from the NARCOMS registry completed the MSISQ-19. Unforced principal component analysis utilizing oblique rotation with Kaiser Normalization validated its construct validity. Results: The scree plot supported a three-component solution, with 63% of total variance explained. The components mirrored the original validation study measuring primary, secondary, and tertiary sexual dysfunction. PCA suggested the scale could be shortened to 15 items, which were found to apply equally well to males and females (with one primary item specific for each sex). The components were moderately intercorrelated (Pearson rs ranged from 0.5 to 0.67). The secondary subscale correlated most highly with self-reported disability ( r (6081) = 0.44, p < 0.001), whereas the tertiary subscale correlated most highly with psychological distress ( r (5992) = –.37, p < 0.001). Cronbach’s alpha for the total scale (0.92) and the subscales (primary, 0.87; secondary, 0.82; tertiary, 0.91) demonstrated good reliability. Conclusion: The revised 15-item MSISQ is a reliable and valid measure of sexual dysfunction in men and women with MS.
