[Prevalence of adjustment disorder, acute and posttraumatic stress disorders as well as somatoform disorders in cancer patients]. / Prävalenz von Anpassungsstörung, Akuter und Posttraumati-scher Belastungsstörung sowie somatoformen Störungen bei Krebspatienten.

We aimed to systematically summarize the empirical evidence on the 4-week-, 12-month-, and lifetime prevalence of adjustment disorders, acute and posttraumatic stress disorders as well as somatoform disorders in cancer patients. We evaluated 64 English or German language original papers and systematic reviews that assessed the prevalence of affective and anxiety disorders using structured clinical interviews published between 1995 and 2010. Adjusted prevalence rates were calculated using a random-intercept model. We found the following pooled adjusted 4-week prevalence rates: For adjustment disorder 12.5% (95% CI 9.9-15.7), for posttraumatic stress disorder 2.6% (95% CI 1.7-4.0), for acute stress disorder 4.8% (95% CI 2.2-10.0) and for somatoform disorders 3.1% (95% CI 1.6-5.8). Our findings show the need for further research on representative studies that take into account the range of psychosocial stressors and supportive care needs.

[Prevalence of affective and anxiety disorders in cancer: systematic literature review and meta-analysis]. / Prävalenz affektiver und Angststörungen bei Krebs: Systematischer Literaturreview und Metaanalyse.

We aimed to systematically summarize the empirical evidence on the 4-week-, 12-month-, and lifetime prevalence of affective and anxiety disorders in cancer patients. We evaluated 89 English or German language original papers and systematic reviews that assessed the prevalence of affective and anxiety disorders using structured clinical interviews published between 1995 and 2010. Adjusted prevalence rates were calculated using a random-intercept model. The pooled adjusted 4-week prevalence of affective disorders was 11.1% (95% CI 8.1-15.1), and 10.8% (95% CI 6.8-16.7) based on German studies. The pooled adjusted 4-week prevalence of anxiety disorders was 10.2% (95% CI 6.9-14.8), and 13.5% (95% CI 7.1-24.3) based on German studies. The findings show the need for further research on representative studies that take into account the range of psychosocial stressors and supportive care needs in addition to the prevalence of mental disorders.

Work-related self-report measures and assessment tools in cancer survivorship: a systematic literature review.

PURPOSE: To systematically review and appraise studies examining self-report questionnaires measuring work-related aspects in cancer patients. METHOD: Literature search methodology: Searches in Embase, PsycINFO, PSYNDEXplus, PSYNDEXplus Tests and PubMed for the period 1990-2011 were completed. Inclusion criteria were as follows: (i) the questionnaire measures work-related aspects; (ii) the questionnaire has been used in at least one study, which involved cancer patient as a relevant target group; and (iii) articles were written in English or German. RESULTS: Twenty-two articles out of 350 records were reviewed and 13 questionnaires identified. The majority of measures cover several dimensions of work-related aspects representing a variety of work-related experiences and constructs such as aspects of the work environment, demands at work and work-related interpersonal relations. Nine of the 13 questionnaires showed good internal consistency whereas subscales of four instruments had fair or poor internal consistency. For 12 out of 13 measures, validity and reliability were tested in non-cancer populations. CONCLUSIONS: The knowledge about reliability and validity of self-report questionnaires measuring work-related aspects in cancer patients is scarce and more high-quality validation studies are needed. Findings further emphasize the need for the development of valid multidimensional measures that are relevant for both research and rehabilitative occupational interventions.
