  • A psychometric evaluation of a Swedish version of the psychopathology inventory for mentally retarded adults (PIMRA).
    Research in developmental disabilities, 2005
    Co-Authors: Carina Gustafsson, K Sonnander
    Abstract:

    Given the difficulties with symptom identification and the assessment of mental health problems in persons with intellectual disabilities (ID) there has been a focus on the development of relevant assessment schedules for persons with ID. A Swedish version of the psychopathology inventory for mentally retarded adults (PIMRA, informant version), an instrument designed for identification of specific mental health problems in persons with ID, was evaluated in terms of inter-rater reliability, internal consistency, item grouping, criterion and concurrent validity based on a sample of 101 adults with different levels of ID. The Swedish version of the PIMRA had low inter-rater agreement on specific items but good agreement on low or high total score. In order to investigate internal validity, principal component analyses (PCA) were conducted in steps. Consequently, the majority of the 26 items, which remained after three PCA analyses, were grouped in a pattern approximating five of the original PIMRA subscales. The present analysis identified no item grouping matching the original Affective disorder subscale. Based on these results a revised Swedish version was developed. The concurrent validity analysis yielded a strong association between the total scores of the PIMRA and Reiss Screen for Maladaptive Behaviour (RSMB), between subscales on both instruments describing psychotic symptoms and between the RSMB subscale Aggressive behaviour and the PIMRA subscale Adjustment problems. The outcome of the criterion validity analysis indicated that individuals with a clinical diagnosis obtained higher total PIMRA scores than individuals without a clinical diagnosis and a comparison between the PIMRA subscale Psychosis and the clinical diagnosis indicating psychoses according to DSM-III-R or DSM-IV yielded a higher specificity than sensitivity measure. The results indicate that the PIMRA had a potential to identify individuals with mental health problems in persons with different levels (mild, moderate and severe) of ID and identify individuals with a specific mental disorder. Thus, professionals might use the PIMRA as a complement in the diagnostic process.

  • Occurrence of mental health problems in Swedish samples of adults with intellectual disabilities
    Social Psychiatry and Psychiatric Epidemiology, 2004
    Co-Authors: Carina Gustafsson, K Sonnander
    Abstract:

    Objective: The aim of this study was to investigate the occurrence of mental health problems in adults with intellectual disabilities (ID) and the number of adults with ID receiving care at general mental health clinics. Method: The Reiss Screen for Maladaptive Behaviour and the Psychopathology Inventory for Mentally Retarded Adults were used to investigate mental health problems in samples from two Swedish counties. Adults with ID receiving psychiatric care at general mental health clinics were investigated via the mental health services register in one county. Results: The overall occurrence of mental health problems in adults with ID ranged from 34 % to 64%. The most common mental health problems were aggressive, self-injurious behaviours, signs of depression, anxiety or adjustment problems. The occurrence of adults with ID among patients receiving out- or in-patient psychiatric care was approximately 1%. Between 70 % and 90% of these persons had a mild level of ID. Conclusion: The overall occurrence of mental health problems was similar to reported overall figures in comparable studies conducted in the US, UK and Denmark. The number of adults with ID registered for out- or in-patient psychiatric care was low compared with the occurrence of mental health problems based on the Screening results.

  • Psychometric evaluation of a Swedish version of the Reiss Screen for Maladaptive Behavior.
    Journal of intellectual disability research : JIDR, 2002
    Co-Authors: C Gustafsson, K Sonnander
    Abstract:

    People with intellectual disability (ID) are afflicted by mental health problems to a greater extent than other individuals, and the coexistence of ID and mental health problems involves diagnostic as well as treatment difficulties. A Swedish version of the Reiss Screen for Maladaptive Behavior (RSMB), an instrument used for identification of mental health problems in people with intellectual disability (ID) was evaluated in terms of inter-rater agreement, internal consistency, item grouping and criterion validity based on a random sample and a clinical group of adults with ID. The Swedish version of the RSMB had moderate-to-low inter-rater agreement on specific items and good internal consistency. The total score was considered to be a fairly reliable measure of a positive or negative result on the RSMB. A principal component analysis yielded seven interpretable components. A close resemblance in sets of items between the Swedish version and the original version of RSMB was found for three subscales: Aggressive Behaviour, Avoidance Disorder and Depression (Behavioural Signs). The outcome of the criterion validity analysis indicated a higher rate of false negatives than false positives. The potential influence of concurrent psychopharmacological treatment is discussed. It is concluded that the Swedish version of the RSMB can be used as intended by staff as a primary Screening device for the identification of mental health problems among people with ID in a Swedish setting.

  • Psychometric properties and normative data of the French developmental behavior checklist - adult version.
    Research in developmental disabilities, 2014
    Co-Authors: Claudio Straccia, Paolo Ghisletta, Jean-jacques Detraux, Koviljka Barisnikov
    Abstract:

    The main aim of this study was to generate psychometric data for the French translation of the Developmental Behavior Checklist - Adult version (DBC-A). In addition, the score distributions were examined by using components of mean-based scores. The DBC-A was administered to 580 adults with intellectual disability recruited in the French-speaking regions of Switzerland and Belgium. A confirmatory factor analysis was performed to evaluate the adjustment of the collected data to the original six-factor model; the internal consistency of the factors was analyzed with Cronbach's alpha. The Reiss Screen for Maladaptive Behavior was used to evaluate the concurrent validity of the instrument. Psychopathology prevalence was also explored. The original factor structure of the DBC-A was replicated, with the internal consistency of the factors ranging from respectable to very good according to the alpha values. When the "Screening" cut-off of the DBC-A was used, the DBC-A highlighted a psychopathology prevalence of 38%, which was close to the frequency provided by the Reiss Screen (36%). These results show the robustness of the DBC-A's psychometric properties. Thus, we recommend the use of this instrument to assess and Screen psychopathology among French-speaking adults with intellectual disability.

    Abstract:

    Abstract The main aims of the present study were to examine the factor structure and the internal consistency of the factors in the French version of the Reiss Screen of Maladaptive Behavior in a French-speaking European sample. The prevalence of psychopathology and the influence of associated factors were also examined. The Reiss Screen was administered to 467 adults (age range: 18–73) with intellectual disability living in the French-speaking regions of Switzerland and Belgium. A confirmatory factor analysis was performed to replicate the original factor structure. Internal consistency was examined by using Cronbach's alpha. Analyses of variance were computed to study the influence of gender, age and Down syndrome etiology. The original factor structure of the Reiss Screen was replicated. The overall rate of psychopathology in the sample was 37%. No linear relationship between age and psychopathology was found. However, adults aged less than 26 years had lower scores than older adults on several psychopathological domains. Males had higher scores than females on the Autism and the Avoidant Disorder subscales. Participants with Down syndrome had lower scores on all domains, with the exception of the Autism subscale. The results of this study suggest that the French version of the Reiss Screen can be a useful tool to detect psychopathology in adults with intellectual disability.
