Intentions : « The objective of the current study was to improve our understanding of the determinants of expressed emotion in the mothers of schizophrenia patients by incorporating aspects of their personality, the patients’ symptom severity, and the mothers’ subjective burden into causal models of CCs [critical comments] and EOI [emotional over involvment]. » (p. 214) Questions/Hypothèses : « With these competing models of CC and EOI at hand, we endeavored to answer the following research questions: 1. To what extent do the initial and the alternative models of CC and EOI fit the data from a sample of mothers of patients with schizophrenia? 2. To what extent is the variance in mothers’ CC and EOI explained by aspects of the patients’ clinical condition, by the mothers’ personality and by their subjective burden? 3. Do maternal personality and patient symptom severity have significant indirect effects on CC and EOI via direct effects on maternal subjective burden? » (p. 214-215)
Échantillon/Matériau : « The 41 patients in this study averaged 31.27 years (S.D. = 8.07 years), with from zero to 10 previous hospitalizations (M = 2.17, S.D.= 1.68). They included 33 men (80.5%) and eight women (19.5%). The sample was primarily French Canadian (46.3%, n = 19) and English Canadian (34.1%, n = 14); the remaining patients were of Haitian origin (n = 3) or second generation Eastern European (n = 5). » (p. 215)
Instruments : - the 45-min abbreviated Camberwell Family Interview (CFI) (Mueser et al., 1992); - the Social Behavior Assessment Schedule (SBAS) (Platt et al., 1980); - the Revised NEO-Personality Inventory (NEO-PI) (Costa and McCrae, 1985; Costa et al., 1991); - the Positive and Negative Syndrome Scale (PANSS) (Kay et al., 1987a,b). Type de traitement des données : Analyse statistique et analyse de contenu
« Our objectives were to determine the extent to which symptoms in the schizophrenia patient and personality in the mother lead to a sense of subjective burden in the mother, and to explain variance in two components of Expressed Emotion. Data on symptom severity (PANSS), mothers’ personality (NEO-PI), subjective burden (SBAS), and Expressed Emotion (CFI) were gathered from 41 schizophrenia outpatients and their mothers. Approximately one quarter of the variance in Critical Comments (CCs) and Emotional Overinvolvement (EOI) was explained using path analysis. Mothers’ CCs were associated with more severe excitement in the patient, with lower Neuroticism, and greater burden in the mother. Higher EOI was explained by greater Conscientiousness and burden in the mother; patient depression had a weak indirect effect on maternal EOI. These results characterize the high EE mother as low in neuroticism and high in conscientiousness with a particular sensitivity to excitement and depression in the patient. » (p. 211)
