Methods: The data of 2, scl 90 r free download, patients within the main treatment group of affective disorders were assessed according to the DSM-IV. Results: There were no significant differences regarding the internal consistency of the SCLR scales and the scales of the short versions.
The assessment of convergent validity revealed high correlations. With regard to the discriminant validity, there were medium correlations. With regard to the sensitivity of change, no significant differences between the scales were found. Conclusions: In summary, the scales of the short versions show mostly satisfactory psychometric properties scl 90 r free download comparison to the scales of the SCLR.
The results support the application of the short versions as screening instruments, especially the BSI, and more economic variants of the SCLR covering a wide range of psychopathological symptoms. Background The Symptom Checklist R SCLR [1] is a widely applied self-assessment instrument for a broad range of mental disorders that assesses the subjective symptom burden in patients with mental disorders, scl 90 r free download. Alongside the high acceptance and extensive worldwide application of the instrument as an outcome instrument in the scl 90 r free download of patients with affective disorders, a number of studies have highlighted the psychometric weaknesses of the SCLR.
This finding is relevant with regard to the practicality of the instrument because results on the factorial validity suggest partial redundancy of the collected data. The development of numerous short versions of the SCLR indicates the need for a more economic instrument. Table 1 gives scl 90 r free download overview of each short version. There are some comparative studies available assessing the validity of individual short versions in different scl 90 r free download. One study by Mller et al.
Mller et al. Compared to the subscales of the SCLR, the subscales of the short versions of the SCLR showed satisfactory psychometric properties in various mental disorders.
Empirical data from health surveys have shown that the prevalence rate of affective disorders ranges from 6. Not only are affective disorders a highly prevalent disorder in the general population, people with scl 90 r free download disorders comprise one of the largest patient groups in inpatient and outpatient psychotherapeutic settings [15].
No empirical data on the appropriateness of the SCLR and its short versions within this large diagnosis group exist. This study should also add substantial information on the concurrent validity of the SCLR and its short versions in patients within the most prevalent subgroup of affective disorders.
The instruments applied in this study were the German version of the SCLR [18] and the German version of the Beck Depression Inventory [19], a widely applied and well-known disorder-specific self-report instrument that assesses the severity of depression symptoms. Statistical analyses.
This study was conducted at one of the largest clinics for inpatients with mental disorders in Germany between and The clinic concept comprises mainly cognitive-behavioural therapy. The study was conducted in line with the Code of Ethics of the World Medical Association Declaration of Helsinki, and approved by the institutional review board of the Schoen Hospital Company.
Cronbachs alpha values of 0. Confirmatory factor analysis was conducted to assess whether the scales postulated by the test authors could be replicated. The mean value differences and correlations were calculated to assess the equivalence of the SCLR and its short versions.
It was expected that the scales and scl 90 r free download total score of the short versions would on the one hand significantly differ from and on the other hand correlate highly with the scales and the total score of the SCLR long version. Therefore, significant correlations with large effect sizes were expected. The size of the correlations was based on the.
To assess the discriminant validity correlations between all other subscales of the SCLR and its subscales with the BDI, the total score was calculated. The effect sizes were interpreted as follows: 0. Furthermore, the six-dimensional scale structure of the SCL was not adequately confirmed in patients with affective disorders, although the RMSEA 0.
The SRMR 0. With regard to the BSI, scl 90 r free download, satisfactory cut-off values were confirmed. The postulated scale structure of the SCL was replicated using confirmatory factor analysis, as all three indices were within the expected range see Table 3. We provided additional material on the covariance matrix for the SCLR and their short versions of the confirmatory factor analyses please see Additional files 1, scl 90 r free download, 2, 3, scl 90 r free download, 4, 5 and 6 as PDF.
Equivalence of the short forms with the SCLR, scl 90 r free download. Internal consistencies were calculated to assess reliability. No significant differences were found between the internal consistencies of the compared scales in a psychometric examination of the calculated coefficients using Fishers z-test based on the large sample size used see Table 2.
Factorial validity of the short forms compared to the SCLR. To assess the practical significance, effect sizes of the calculated mean value differences were also calculated. Convergent and discriminant validity of the short forms compared to the SCLR. Table 3 displays the results of the confirmatory factor analysis. Moreover, the assessment of the BSI scale structure in patients with affective disorders did not reveal a homogenous picture.
With regard to discriminant validity, theoretically expected low correlations were not found, but only for the SCL and the BSI we found lower correlations see Table 5. An assessment of the sensitivity to change showed only one larger deviation for the SCL of pre-post effect sizes see Table 6 compared to the effect size of the SCLR. For all other scales, the comparisons showed only minor differences in calculated effect sizes see Table 6.
With regard to reliability, no significant difference regarding the internal consistencies of the SCLR and its short versions was expected. As expected, the reliability values were decreased with decreasing item numbers but highest for the GSI of the SCLR and its short versions, scl 90 r free download. Regarding the factorial validity, the originally postulated scale structure of the SCLR by Derogatis [4] was not supported in this study on patients with affective disorders, which is in line with numerous previous studies [2,26,27].
Furthermore, the assessment of the BSI scale structure showed an insufficient model fit, scl 90 r free download, leading to a rejection of the postulated model.
Fit indices of the SCL scale structure supported a better fit of the scale structure but were not regarded as satisfactory. These results were largely in agreement with findings of Hardt et al. The BSI also showed largely satisfactory results regarding its factorial validity in patients with affective disorders. In line with the findings of Harfst et al. The one-dimensional scale structure of the SCL-K-9 and the dimensional scale structure of the BSI were also supported in confirmatory factor analysis.
An assessment of the equivalence of scale values of the short versions and the SCLR in patients with affective disorders showed, as expected, no significant differences. Overall, it can be concluded that the symptom severity values of the SCLR scales are comparable to values of the short versions. The convergent validity of the SCLR and its short versions can be regarded as satisfactory. There were consistently significant correlations with at least large effect sizes. These results support the suitability of the SCLR short versions as a screening instrument to cover a wide range of scl 90 r free download symptoms in patients with affective disorders without a substantial loss of information.
Similar to the findings of the factorial validity of the SCLR and the majority of its short versions, the discriminant validity was also not regarded as satisfactory.
The only exception was the SCL [8], in which the two subscales somatisation and phobic anxietycorrelated. Although this correlation was still of at least medium effect size, it was nonetheless substantially lower in comparison to the scales scl 90 r free download the short versions and the SCLR.
Therefore, the discriminant validity of the SCLR and its short versions in patients with affective disorders cannot be regarded as satisfactory. The assessment of sensitivity to change was expected to show no marked difference between the SCLR and its short versions in patients with affective disorders.
The results of sensitivity to change showed only small differences. Moreover, the results showed, as expected, that effect sizes of the SCLR depression scale and its short versions were highest compared to other scales e. This finding supports the. Overall, it can be concluded that the short versions are a more economic variant of the SCLR, although for the SCLR, only the interpretation of the total score can be recommended.
This finding is in line with empirical findings from other studies [28,29], which also recommend the use of the SCLR as a screening instrument using the global index.
However, the present study shows that the more economic short versions can also be applied with similar psychometric properties, particularly validity, scl 90 r free download, in patients with affective disorders. Furthermore, the reported empirical findings show that the three-dimensional factor structure of the BSI and the SCL [8] was replicated. Therefore, from a psychometric perspective, it can be concluded that the BSI and the SCL are not only a more economic alternative but can also be regarded as a psychometric improvement.
The SCL-K-9, scl 90 r free download, with only 9 items, does not have a broad range of measurement and only limitedly contributes to the assessment of a wide range of psychopathological symptoms within the context of a heterogeneous clinical sample. Moreover, the assessment of changes within the therapy process, an important criterion for outcome instruments, is also fulfilled across all short versions.
A number of limitations of this study need to be noted. Our results showed high correlations between the scores of the SCLR and its short versions. If we had advised the patients to fill out the versions separately, this high intercorrelation may have decreased. Nonetheless, this procedure appeared feasible against the background of missing comparable studies on patients with affective disorders.
Regarding the generalisability of our results, we compared the SCLR and its short versions in a widely representative sample of inpatients with affective disorders undergoing psychotherapeutic treatment in Germany. There is a need for the further psychometric evaluation of patients with affective disorders in other settings e.
