“…In line with other QoL research in severely mentally ill patients, low QoL ratings were found in the domains of social contacts, finances and general life-satisfaction, as well as for the subscale leading a “normal” life . This stands in contrast to the findings of generic QoL scales that repeatedly found high satisfaction in schizophrenic patients – even under poor living conditions [7,8,40]. It should be noted, that despite a tendency to rate ones’ own live rather positively, most subscales’ means of the QLiS centre around the theoretical mean of five.…”

BackgroundThe aim of the project was to develop an instrument for the assessment of subjective quality of life specific to schizophrenic persons on the basis of patients’ views on their own life and on sound psychometric principles.MethodsThe project applied a six-step multiphase development process with six distinct studies. (1) The elicitation of schizophrenic persons’ views on their quality of life was based on open-ended interviews with interviewees from different settings (acute ward inpatients, long-term care patients, community care patients; n = 268). (2) A cross-sectional study with schizophrenic and healthy persons was conducted to quantify the relative importance of the various aspect of quality of life that emerged from the qualitative study (n = 143). (3) We conducted an empirical comparison of response formats with schizophrenic persons (n = 32). (4) A scale construction- and reliability-testing study was performed (n = 203) as well as (5) a test-retest reliability study (n = 49). (6) The final questionnaire (QLiS, quality of life in schizophrenia) was tested in an additional study on convergent and discriminant validity (n = 135).ResultsThe QLiS comprises 52 items (plus 2 optional items related to work) in 12 subscales: social contacts, appreciation by others, relationship to family, appraisal of pharmacotherapy, appraisal of psychopathological symptoms, cognitive functioning, abilities to manage daily living, appraisal of accommodation/housing, financial situation, leading a ’normal‘ life, confidence, general life-satisfaction. An item response format with four response categories was preferred by the schizophrenic persons. The mean values of the subscales clustered around the theoretical mean of the subscales and only minimal ceiling effects were found. The reliability (test-retest-reliability and internal consistency) was with one exception > .70 for all subscales.ConclusionTaking the low numbers of items per subscale into account, the QLiS can be regarded as an accurate assessment instrument of subjective quality of life in schizophrenia with good content validity.

“…In another study by Ginsberg et al, [24], in which patients with schizophrenia were asked about their expectations concerning the treatment, it became clear that besides the alleviation of symptoms, patients required an improvement on social functioning such as more daily activities, social contacts and career opportunities. The improvement of psychological and social performance also means successful personal, social and professional reintegration [25,26]. …”

Correlation between the Personal and Social Performance scale (PSP) and the Positive and Negative Syndrome Scale (PANSS) in a Greek sample of patients with schizophrenia

BackgroundPsychosocial dysfunction is one of schizophrenia’s core features, often leading to a deprecation of independent living and significant failure to maintain a competent quality of life. Cognitive and occupational performance as well as psychosocial functioning is moreover recognized as determinants of treatment response. Therefore, the elaboration of measures regarding social performance besides scales that assess psychopathology is essential. The Personal and Social Performance (PSP) scale has been found to be as much valid as reliable for assessing social functioning in the acute and stable stage of schizophrenia. The aim of this study was to estimate the correlation between the PSP and Positive and Negative Syndrome Scale (PANSS) (convergent validity) in patients with schizophrenia during routine clinical practice.MethodsA longitudinal study with a six-month follow-up is presented. Correlation between the PSP scale and the Positive and Negative Syndrome Scale (PANSS) was conducted in a Greek sample of 2010 patients with schizophrenia in outpatient setting in two successive visits. PANSS and PSP scales were used for the assessment of psychopathological symptoms and social and personal functioning.ResultsThe PSP subscales scores were well correlated with each other with Spearman correlation coefficients (r) ranging from 0.56 to 0.76 on both visits in three out of the four main areas, whereas in the category of “disturbing and aggressive behavior” the correlations were lower but still significant. Furthermore, total PSP score showed high association to PANSS total score in the first (r = -0.59) as well as in the second visit (r = -0.50). Regression analysis showed that one point decrease of PANSS’s total score is associated with a 0.42 points increase on the PSP scale. PSP and PANSS scales exhibited high convergent validity.ConclusionsThe PSP could provide additional valuable information in the assessment of schizophrenia related social functioning and treatment response.

“…Der Zusammenhang zwischen Le− bensqualität und Depression ist jedoch auch von anderen Krank− heitsbildern und aus der Allgemeinbevölkerung bekannt [26]. Da depressive Verstimmungen bis zu 73 % der Varianz in den LQ− Bewertungen einer Stichprobe erklären, sollte das Ausmaß de− pressiver Symptomatik immer mit erfasst werden, um überprü− fen zu können, inwieweit die gemessenen LQ−Werte darauf zu− rückzuführen sind [27]. Außerdem muss berücksichtigt werden, dass Selbsteinschätzun− gen gesundheitsbezogener Lebensqualität nicht das Ergebnis ei− nes rekursiven Beurteilungsprozesses sind, sondern das Resultat der Anpassung eigener Ansprüche und Erwartungen an objekti− ve Gegebenheiten [28].…”

“…Außerdem muss berücksichtigt werden, dass Selbsteinschätzun− gen gesundheitsbezogener Lebensqualität nicht das Ergebnis ei− nes rekursiven Beurteilungsprozesses sind, sondern das Resultat der Anpassung eigener Ansprüche und Erwartungen an objekti− ve Gegebenheiten [28]. Das bedeutet, dass auch Kranke, die un− ter sehr ungünstigen Bedingungen leben, sehr zufrieden mit ih− rem Leben sein können, weil sie das Niveau ihrer Erwartungen weit unter das Aspirationsniveau Gesunder abgesenkt haben [27,29]. Subjektive LQ−Werte, die unter dem Niveau der Allge− meinbevölkerung liegen, können somit zwar als Indikator für ein Versorgungsdefizit gelten, aber Werte, die dem Niveau der Allgemeinbevölkerung entsprechen, sind kein hinreichendes In− diz für eine gute Versorgungsqualität [30].…”

“…Wenn dies der Fall ist, wäre nach einer erfolgreichen Intervention kurzfristig mit einer LQ−Verbesserung zu rechnen, aber mittelfristig könnte es sogar zu einer Verschlechterung kommen, weil das Aspirationsniveau der Erkrankten infolge der verbesserten Lebensumstände gestie− gen ist [30]. Versorgungseffekte müssen deshalb in dem Zeit− raum erfasst werden, der vergeht, bis sich die Patienten an die neuen Umstände adaptiert haben [27].…”
