BackgroundThe BSI-18 contains the three six-item scales somatization, depression, and anxiety as well as the Global Severity Index (GSI), including all 18 items. The BSI-18 is the latest and shortest of the multidimensional versions of the Symptom-Checklist 90-R, but its psychometric properties have not been sufficiently clarified yet.MethodsBased on a representative sample of N = 2516 participants (aged 14–94 years), detailed psychometric analyses were carried out.ResultsThe internal consistency was good: Somatization α = .82, Depression α = .87, Anxiety α = .84 and GSI α = .93. Confirmatory factor analysis supported the three scales as second-order and GSI as first-order factors. The model fit based on RMSEA is good but that model fit based on CFI and TLI are too low.ConclusionsTherefore, it is a very short, reliable instrument for the assessment of psychological distress. The BSI-18 can be used to reliably assess psychological distress in the general population. However, further studies need to evaluate the usefulness of standardization in clinical samples.

The short version of the Brief Symptom Inventory (BSI-18) is an easily applicable, reliable and valid self-report measure in wide international use. It assesses the syndroms of somatisation, depression and anxiety by means of 6 items each. For the psychometric evaluation of the German translation, undergraduate students, non-clinical subjects and psychosomatic outpatients were administered the BSI-18. Across these populations, all scales showed satisfactory to good internal consistencies (Cronbachs alpha ranged between 0.63 and 0.93). The item-total correlation as item discrimination index was sufficiently high, patricularly in the patient sample (rit ≥ 0.40). The correlations of the BSI-18 with measures of similar dimensions were moderate to high indicating a good convergent validity. Criterion-related validity was established in so far that patients scored significantly higher in all BSI-18 scales than did the non-clinical samples. With some exceptions, the German translation of the BSI-18 has similarly good psychometric qualities as the American original.

The Symptom Check-List-90-R (SCL-90-R) is a widely used psychological status symptom inventory. The properties of the German SCL-90-R version were studied in two clinical samples: psychosomatic outpatients and primary care patients. The data were compared with a German community sample. The internal consistency, measured by Cronbach's alpha coefficients, was found to be high, for the global scale and all original subscales. Mokken scale analysis indicated hierarchical structure for most of the subscales. Concurrent validity, evaluated by studying the relationship between the SCL-90-R subscales and the Inventory of Interpersonal Problems (IIP-C) and the General Health Questionnaire (GHQ-12) was also high. On the basis of receiver operating characteristic (ROC) analyses, it was found that the SCL-90-R was able to differentiate between subjects known to have a given psychological disorder and those who do not. Results of exploratory and confirmatory factor analysis failed to support the original nine factor model and two subsequent factor models. The strong interdependence of the original subscales and the strong first unrotated factor of the exploratory factor analyses raised concern regarding the multi-dimensionality of the SCL-90-R subscales. We concluded that the SCL-90-R is a useful tool for measuring psychological status, measuring change in outcome studies, or screening for mental disorders.

Donors viewed LRLT positively. Quality of life after donation did not change. However, donors had a prolonged period of physical rehabilitation, and 41% experienced financial disadvantages.

Seen from the donor's perspective, LDKT is a relatively safe procedure. However, increased rates of donors with mental distress and intra-familial conflicts emphasize the need for a careful selection process. Regular postdonation psychosocial screening and provision of specific interventions to those in need are recommended. Donors should not suffer from financial and occupational disadvantages resulting from donation.
