Validation of the Social Appearance Anxiety Scale in Female Eating Disorder Patients

In the present study, we investigated the psychometric properties of the Social Appearance Anxiety Scale (SAAS) in a sample of 60 female eating disorder patients (M_age = 27.82, SD = 9.76). The SAAS was developed to assess anxiety about being negatively evaluated for one's appearance. All patients completed the SAAS, the Eating Disorder Inventory—2, the Physical Health Questionnaire—9 Depression and the Dimensional Assessment of Personality Psychopathology. The SAAS demonstrated a one‐factor structure and a high internal consistency. The SAAS was significantly positive in relation to body mass index, drive for thinness and body dissatisfaction. Concerning personality dimensions, the SAAS was positively related to emotional problems (e.g. depression, anxiety) and interpersonal problems (e.g. suspiciousness, submissiveness). Findings suggest that the SAAS is a psychometrically sound instrument to assess anxiety about being negatively evaluated about one's appearance in a sample of eating disorder patients.

Preliminary evaluation of psychometric properties of the Finnish Borderline Personality Disorder Severity Index: Oulu-BPD-Study

Abstract

Background: Borderline personality disorder (BPD) is a severe disorder decreasing the functional ability of the patient and places an extensive burden on the healthcare system. There is a need for a reliable and valid instrument with which unstable recent BPD symptoms can be assessed in a short-term perspective, and which is applicable for clinical evaluations and treatment-outcome research. Aims: We evaluated the psychometric properties of the Borderline Personality Disorder Severity Index IV (BPDSI-IV) interview in a sample of Finnish BPD patients. Our study is a part of the randomized, monocentre Oulu-BPD trial, which compares the effectiveness of treatment by experts with treatment as usual. Methods. Patients (n = 71) were enrolled in a 2-year randomized controlled trial. The BPDSI-IV was used to assess recent manifestations of BPD. The internal consistency of the BPDSI-IV in the Finnish patient sample was analysed with Cronbach's alpha coefficient and mean item-total correlation. Discriminant validity was examined by comparing the Finnish BPD patient sample with the Dutch BPD patient and non-patient samples. Results. The Cronbach's alphas ranged from 0.58 to 0.79 being highest in Dissociation and lowest in Relationships. A total of five subscales out of nine exceeded the acceptable limit (≥ 0.70). With respect to mean item-total correlation, seven out of nine subscales had an acceptable correlation ≥ 0.30. Conclusions. The BPDSI-IV interview was applied for the first time in a Finnish sample of BPD patients. It appears to be a useful instrument for measuring and following the severity and the change of symptoms of patients with BPD.     

Psychometric evaluation of a scale to assess satisfaction with life among people with intellectual disabilities living in community residences

Background In the context of a health intervention among people with intellectual disabilities (ID), there was a need to assess satisfaction with some aspects of life, in order to monitor both potential positive and negative effects of the intervention. The aim of the present study was to develop and evaluate an easily administered scale for assessing satisfaction with home environment and leisure time among people with mild or moderate ID, living in community residences. Methods A number of questions were constructed to measure satisfaction with home environment and leisure time. The questions were answered by 132 adults with mild or moderate ID, living in community residences in Sweden. The dimensionality of the scale was evaluated by factor analysis, and the reliability was estimated using Cronbach's alpha coefficients. Results The analysis supported a four‐factor solution with 12 items. The four factors were: (I) Satisfaction with housing environment; (II) Satisfaction with life; (III) Satisfaction with meals; and (IV) Satisfaction with recreational activity. The four factors explained almost 70% of the variance in the data set. Cronbach alpha coefficients for all scales were above 0.70, indicating that the reliabilities of the scales were satisfactory. Correlations between the four sub‐scales ranged from 0.06 to 0.52, indicating low to moderate inter‐correlations between the four sub‐scales. Conclusion The scale has fairly good psychometric properties and is easy to administer. The scale, which can be further improved, can be an important resource in health intervention studies.     

Reproducibility of the items on the Stroke Specific Quality of Life questionnaire that evaluate the participation component of the International Classification of Functioning,Disability and Health

Purpose: To evaluate the reproducibility of the Stroke Specific Quality of Life (SS-QOL) items that address the participation component of the International Classification of Functioning, Disability and Health (ICF) and analyse the correlation between the subscore of these 26 items and the total SS-QOL score.

Methods: Seventy-five stroke survivors participated in this study. Reproducibility was evaluated using the intraclass correlation coefficient (ICC_2,1), standard error of measurement (SEM), minimum detectable change (MDC) and the Bland–Altman plot. The correlation between the subscore of the 26 items and the total SS-QOL score was analysed using Spearman’s correlation coefficients (rho) and simple linear regression. An alpha risk?≤?0.05 was considered for all analyses.

Results: The SS-QOL items that address the participation component of the ICF demonstrated excellent reliability (intra-rater ICC_2,1?=?0.96; inter-rater ICC_2,1?=?0.95). The SEM and MDC were adequate. The Bland–Altman plot demonstrated satisfactory agreement. A significant and strong correlation (rho?=?0.83) was found between the 26 SS-QOL items that address participation and the total SS-QOL score. Moreover, the evaluation of participation was found to explain 73% of the evaluation of health-related quality of life.

Conclusion: The 26 SS-QOL items that address the participation component of the ICF demonstrated adequate reproducibility. Thus, participation, which represents the social aspects of functionality, can be adequately evaluated with these items.

• Implications for Rehabilitation

• The 26 Stroke Specific Quality of Life items that address participation proved to be reproducible for the analysis of social participation following a stroke.

• The findings can lead to a better understanding of the social participation of individuals with chronic hemiparesis and assist in the establishment of adequate treatment for such individuals.

• The rehabilitation process can be directed towards more specific goals focused on the patient expectations, thereby contributing to greater humanization and effectiveness of treatment to improve social participation following a stroke.

     

Validation of the eleven-point pain scale in the measurement of migraine headache pain

The four-point pain scale (none, mild, moderate, severe) and the 11-point pain scale (0 = no pain, 10 = pain as bad as it could be) have been used in migraine studies to assess treatment efficacy. The primary objective of this study was to investigate the validity and responsiveness of the 11-point pain scale using the four-point pain scale as a benchmark. Using data from 95 migraine patients recruited from headache clinics, this study found that 11-point pain scale scores were highly correlated with four-point pain scores. The correlations between the pain scales were significantly higher than the correlations with quality of life measures such as functional ability and emotional feelings. The 11-point pain scale was 55% more sensitive than the four-point pain scale in detecting clinically important differences. The strong linear relationship between the two pain scales allowed researchers to transform four-point pain scores to 11-point pain scores using regression weights.     

Development and initial validation of the Perceived Scarcity Scale

Though socio‐economic status (SES) partially explains the experience of stress and health outcomes, most research to date has relied on a small number of traditional indicators that fail to capture the full domain of socioeconomic factors. The recent reconceptualization of perceived scarcity is proposed as a subjective indicator of SES when attempting to predict both stress and health outcomes. Although a conceptualization of perceived scarcity has been advanced, a psychometrically sound scale is needed to assess the utility and scientific import of this concept. No such scale exists. Therefore, the current paper describes the development, psychometric properties, and initial validation of the Perceived Scarcity Scale (PScS). Four studies using traditional scale development processes were employed to develop (Studies 1 and 2) and provide an initial validation (Studies 3 and 4) for the PScS. Results support the existing model of perceived scarcity and indicate that the measure is valid. Moreover, the scale predicted concurrent perceived stress, as well as longitudinal ratings of perceived stress, global health, quality of life, and symptoms of depression and anxiety. The development of the new scale provides clinicians and researchers with a brief, validated measure that can assess the level of perceived scarcity individuals currently experience.     

ANXIOUS FORMS OF DEPRESSION

Previous research has described distinctive features for anxious and nonanxious forms of major depression. The concept of “mixed anxiety depression disorder” (MADD) refers to a milder degree of the anxious form of depression, since the depressive symptoms fall short of the number required for a diagnosis of major depression. It is argued that this can be thought of as a subclinical form of anxious depression, rather than a separate disorder in its own right. In view of its substantial prevalence in general medical settings, its associated disability and its public health importance, it deserves to be recognized, and seen as being continuous with the more severe forms of anxious depression. It will therefore be included in the Field Trials of the version of the ICD‐11 (where ICD is the International Classification of Disease) intended for primary care. It is argued that current anxiety, depression (without anxiety), and anxious depression would cover most of the psychologically distressed patients seen in general medical settings, using a pseudodimensional system.
