Psychometric properties of the Spanish structured interview of personality organization revised (STIPO-R) in a clinical and community sample

Psychometric properties of the Persian version of the somatic symptom disorder–B Criteria Scale (SSD-12) in community and clinical samples

The purpose of this study was to develop the Karitane Family Outcomes Tool (KFOT), a brief parent-report questionnaire to measure outcomes of Australian Early Parenting Centres (EPCs) and similar programmes worldwide. The study was conducted in two stages. In Stage One, an initial item pool (80 items) was developed via focus group discussions with clinical experts and parents. In Stage Two, three samples of parents were recruited (online community sample: n = 849, clinical sample 1: n = 141, clinical sample 2: n = 109). The online community sample completed the 80-items and then non-normally distributed items were culled, leaving a total item pool of 57 items. The online community sample was then split into two subsamples (subsample 1: n = 650, subsample 2: n = 199). Exploratory factor analysis (EFA) was then conducted on online community subsample 1 and confirmatory factor analysis (CFA) on online community subsample 2 and clinical sample 1. Using clinical sample 2, concurrent validity was assessed by examining correlations between KFOT factor scores with scores on the Parenting Stress Index. Finally, discriminant validity was assessed by examining the KFOTs sensitivity to change following EPC intervention and by comparing KFOT scores of clinical and community samples. EFA revealed 13 items loading onto three factors: "Parental feelings," "Reading cues & meeting the child's needs" and "Perceptions of child behaviour." The factor structure was confirmed using CFA in both the community and clinical samples. Significant differences on all three KFOT factors and on the total score were found between the clinical and community samples, suggesting that the scale is able to discriminate between clinical and nonclinical groups. Significant differences were also found between pre- and postintervention scores, and between pre- and follow-up scores, on all three KFOT factors, providing further indication of discriminant validity. The KFOT factors correlated in the expected direction with scores on the Parenting Stress Index, showing concurrent validity. Results indicate that the KFOT is a brief, valid and reliable parent-report scale that can be used by nurses to evaluate outcomes of EPC and similar parenting programmes.

This paper presented the Turkish version of the Depression Anxiety Stress Scale-21 (DASS-21) in community and clinical samples, examined its psychometric properties. Construct validity and concurrent validity were conducted in validity studies. Depression Anxiety Stress Scale-42 (DASS-42) was used for concurrent validity. In reliability analysis, the instruments internal consistency and re-test reliability were studied. Results of explanatory factor analyses demonstrated that 21 items yielded three-factors. Results of confirmatory factor analyses for three-dimensional model showed that acceptable fit index values in community sample and perfect fit index values in clinical sample. Factor loadings ranged from .42 to .72. In the concurrent validity, significant positive relationships were found between DASS-42 and DASS-21. Cronbach alpha internal consistency coefficient was found as α= .87 for depression sub-scale, α= .85 for anxiety sub-scale and α= .81 for stress sub-scale in clinical sample. Moreover, test-retest reliability coefficient was obtained as r=.68 for depression sub-scale, r=.66 for anxiety sub-scale and r=.61 for stress sub-scale in community sample, and corrected item-total correlations ranged from .43 to .77 in clinical sample. In second study, DASS-21 discriminated the patients (depression mean score=10.83; anxiety mean score=10.39; stress mean score=11.85) from the healthy subjects (depression mean score=5.88; anxiety mean score=5.37; stress mean score=7.90) well (U=5310.50; 4748.50; 5562.50, p=0.00). According to psychometric properties, DASS-21 is a reliable and valid instrument in the assessment of depression, anxiety, stress levels. [JCBPR 2018; 7(1.000): 19-30]

Objective: This research is primarily conducted to determine the psychometric properties of the Beliefs about Emotions Scale (BES) in community and clinical samples. The BES is a scale measure used for evaluating individuals' beliefs in terms of how acceptable it is for them to experience and express their emotions. Method : This study was conducted on two separate samples. In the first part, 300 individuals were selected from a general sample in Tehran using the quota sampling method. For the second part of the study, we used purposive sampling to gather data from 119 patients suffering from Major Depressive Disorder (MDD) and 121 patients from Somatic Symptoms Disorder (SSD), whose disorders were diagnosed based on the DSM-5 diagnostic criteria. The BES structural validity was examined through Confirmatory Factor Analysis (CFA). Additionally, test-retest composite and internal consistency indices were explored to investigate the reliability of the BES score. Finally, the associations of the BES score with the Hospital Anxiety and Depression Scale (HADS), Young Schema Questionnaire (YSQ), Multidimensional Perfectionism Scale (MPS), Difficulties in Emotion Regulation Scale (DERS), and Emotion Regulation Questionnaire (ERQ) scores were highlighted to investigate the discriminant and convergent validity of the BES score. Results: According to CFAs, the one-factor model for the BES demonstrated a good fit with the data collected from both the clinical and community samples. The internal consistency (Cronbach's alpha) was satisfactory in the community sample (α = 0.84) and the clinical samples of SSD (α = 0.86) and MDD (α = 0.83). The community sample demonstrated high overall test-retest reliability (ICC = 0.93, P < 0.001; 95% CI: 0.89 - 0.95). In terms of convergent validity, the findings confirmed that in the MMD sample, there was a significant relationship between the BES and almost all measures (including Depression (r = 0.39, P < 0.01), Anxiety (r = 0.21, P < 0.05), Self-Sacrifice (r = 0.27, P < 0.01), MPS-total score (r = 0.22, P < 0.05), DERS total score (r = 0.50, P < 0.01), and Suppression (r = 0.38, P < 0.01). However, in the SSD group, this finding was not found. Conclusion: The results demonstrated that the Persian BES is a reliable and valid scale of maladaptive beliefs about emotions which could be implemented for both clinical and research aims.

Psychometric properties of the child and parent versions of Spence Children's Anxiety Scale in a Danish community and clinical sample

The Level of Personality Functioning Scale–Self-Report (LPFS-SR) operationalizes Criterion A of the DSM-5 Alternative Model for Personality Disorders. The current study aimed 1) to examine the internal consistency of the Portuguese version of the LPFS-SR in a community sample and a clinical sample, 2) to compare non-clinical participants (N = 282, Mage = 48.01, SD = 10.87) with two samples of clinical participants, one composed of patients with a personality disorder diagnosis (PD sample, n = 40, Mage = 46.18, SD = 13.59) and the other of patients with other psychiatric diagnoses (OD sample, n = 148, Mage = 49.49, SD = 11.88), with respect to LPFS-SR dimensions and total score, 3) to examine the capacity of the LPFS-SR to discriminate between samples through the ROC curve analyses, and 4) to examine the factor structure of the Portuguese version of the LPFS-SR. The Portuguese version of the LPFS-SR revealed adequate internal consistency results, akin to the original data, in the community and clinical samples. The community sample differed significantly from both clinical samples in all the LPFS-SR dimensions and total score. The ROC curve analysis indicated an optimal cut-off for the total score of 272.00, corresponding to a sensitivity of 75% and a specificity of 89%, in the PD vs. community samples. The LPFS-SR total score discriminative capacity between the PD and OD samples was lower, albeit also significant (area-under-the-curve of .63; p = .027; 95% CI: .52-.74). The current study provided evidence of the LPFS-SR’s unidimensionality in both community and clinical samples. Although this study has limitations, its findings contribute to a deeper understanding of the LPFS-SR construct, as well as to its cross-cultural validation.

Social Phobia and Separation Anxiety Symptoms in Community and Clinical Samples of Children and Adolescents

The aim of this study is to adapt Perceived Devaluation- Discrimination (PDD) scale for Turkish language and culture. Participants from clinical and community populations were included in the study. The community sample consisted of 145 healthy individuals from the general community and the clinical sample consisted of 85 individuals with chronic psychiatric disorders. Psychometric properties of the Turkish version of PDD were assessed in the general community and clinical samples. Exploratory factor analysis, confirmatory factor analysis, internal consistency analysis, convergent and discriminant validity analyses were conducted. As a result of exploratory factor analysis, a two-factor structure for PDD emerged in both the general community and clinical samples. Confirmatory factor analysis also supported the two-factor structure in both samples. These factors were named as Perceived Discrimination and Negative Evaluation and Perceived Acceptance and Non-negative Evaluation subscales. Cronbach's alpha values for PDD were 0.76 in the general community sample and 0.79 in the clinical sample. Alpha values of PDD subscales ranged between 0.72 and 0.77 in both samples. While convergent and discriminant validity tests provided partial support for construct validity of PDD in the general community sample, the convergent validity tests conducted with the clinical sample provided evidence for validity of PDD. Based on the results of the present study, it has been demonstrated that the Turkish version of PDD is reliable and valid and can be used with community and clinical samples to measure perceived devaluation and discrimination.

The Development and Well-Being Assessment (DAWBA) is a novel package of questionnaires, interviews, and rating techniques designed to generate ICD-10 and DSM-IV psychiatric diagnoses on 5-16-year-olds. Nonclinical interviewers administer a structured interview to parents about psychiatric symptoms and resultant impact. When definite symptoms are identified by the structured questions, interviewers use open-ended questions and supplementary prompts to get parents to describe the problems in their own words. These descriptions are transcribed verbatim by the interviewers but are not rated by them. A similar interview is administered to 11-16-year-olds. Teachers complete a brief questionnaire covering the main conduct, emotional, and hyperactivity symptoms and any resultant impairment. The different sorts of information are brought together by a computer program that also predicts likely diagnoses. These computer-generated summary sheets and diagnoses form a convenient starting point for experienced clinical raters, who decide whether to accept or overturn the computer diagnosis (or lack of diagnosis) in the light of their review of all the data, including transcripts. In the present study, the DAWBA was administered to community (N = 491) and clinic (N = 39) samples. There was excellent discrimination between community and clinic samples in rates of diagnosed disorder. Within the community sample, subjects with and without diagnosed disorders differed markedly in external characteristics and prognosis. In the clinic sample, there was substantial agreement between DAWBA and case note diagnoses, though the DAWBA diagnosed more comorbid disorders. The use of screening questions and skip rules greatly reduced interview length by allowing many sections to be omitted with very little loss of positive information. Overall, the DAWBA successfully combined the cheapness and simplicity of respondent-based measures with the clinical persuasiveness of investigator-based diagnoses. The DAWBA has considerable potential as an epidemiological measure, and may prove to be of clinical value too.

BackgroundMolecular monitoring of parasite resistance has become an important complementary tool in establishing rational anti-malarial drug policies. Community surveys provide a representative sample of the parasite population and can be carried out more rapidly than accrual of samples from clinical cases, but it is not known whether the frequencies of genetic resistance markers in clinical cases differ from those in the overall population, or whether such community surveys can provide good predictions of treatment failure rates.MethodsBetween 2003 and 2005, in vivo drug efficacy of amodiaquine or chloroquine plus sulphadoxine-pyrimethamine was determined at three sites in Papua New Guinea. The genetic drug resistance profile (i.e., 33 single nucleotide polymorphisms in Plasmodium falciparum crt, mdr1, dhfr, dhps, and ATPase6) was concurrently assessed in 639 community samples collected in the catchment areas of the respective health facilities by using a DNA microarray-based method. Mutant allele and haplotype frequencies were determined and their relationship with treatment failure rates at each site in each year was investigated.ResultsPCR-corrected in vivo treatment failure rates were between 12% and 28% and varied by site and year with variable longitudinal trends. In the community samples, the frequencies of mutations in pfcrt and pfmdr1 were high and did not show significant changes over time. Mutant allele frequencies in pfdhfr were moderate and those in pfdhps were low. No mutations were detected in pfATPase6. There was much more variation between sites than temporal, within-site, variation in allele and haplotype frequencies. This variation did not correlate well with treatment failure rates. Allele and haplotype frequencies were very similar in clinical and community samples from the same site.ConclusionsThe relationship between parasite genetics and in vivo treatment failure rate is not straightforward. The frequencies of genetic anti-malarial resistance markers appear to be very similar in community and clinical samples, but cannot be used to make precise predictions of clinical outcome. Thus, indicators based on molecular data have to be considered with caution and interpreted in the local context, especially with regard to prior drug usage and level of pre-existing immunity. Testing community samples for molecular drug resistance markers is a complementary tool that should help decision-making for the best treatment options and appropriate potential alternatives.

Intermittent explosive disorder and eating disorders: Analysis of national comorbidity and research samples

Emotion Regulation (ER) and Suicide Crisis Syndrome (SCS) are psychological processes involved in suicide. Within ER, both the use of rumination and dysfunctional emotion beliefs are associated with suicide. SCS, a pre-suicidal mental state involving cognitive and affective dysregulation, is related to short-term suicide risk. Here, we first examined associations between ER (beliefs about the uncontrollability of emotions and rumination), SCS and suicide behavior, and second, we test a multistep model in which ER factors are linked to suicide behavior through SCS. We conducted two cross-sectional studies to address this issue by self-reports. Study 1 used a community sample (N = 421). Study 2 used a clinical sample (N = 70). Results from both studies showed that beliefs about the uncontrollability of emotions and rumination were associated with higher levels of SCS symptoms and suicide behavior, and that SCS was associated with suicide behavior. In addition, path analyses showed that uncontrollability beliefs were linked to rumination, which in turn was associated with SCS, and this variable mediated the association between ER factors and suicide ideation (in both community and clinical samples) and suicide attempts (in the community sample). As we expected, in both samples, uncontrollability of emotions and rumination were positively related with SCS and suicide behavior. We emphasize the importance of addressing uncontrollability beliefs and rumination in suicide prevention.

The factor structure of the Reynolds Child Depression Scale (RCDS; Reynolds, 1989), analyzed by confirmatory factor analysis and the scale's psychometric characteristics in a sample of 315 participants (140 boys and 175 girls) and a clinical sample of 62 participants (37 boys and 25 girls) between 10 and 12 years old, are presented. Two models are tested with confirmatory factor analysis: a one-factor model and a five-factor model. Both models show a good fit, but the one-factor model was chosen because it is the most parsimonious. The reliability coefficient ranged from .87 (at test) to .89 (at retest) in the community sample, and was .90 in the clinical sample (at test). Test-retest reliability was .66 in the community sample. Concurrent validity with other self-reports that measure depressive symptomatology was high, both in the community sample (.76) and the clinical sample (.71). There were no significant sex differences but there were differences due to age (school grade).
