A quantitative measure for expressed emotion

Cognitive functioning and expressed emotion among patients with first-episode severe psychiatric disorders

Expressed emotion (EE) in families is able to predict the clinical outcome of patients with schizophrenia and mood disorders. However, the origins of EE and its interactions with the patient's clinical characteristics are not clear. In this respect, cognitive functioning of schizophrenic and mood-disorder patients has yielded contradictory results. In this cross-sectional study, we examined a sample of 42 consecutive first-episode patients with schizophrenia-related psychoses and severe mood disorders. Forty-two relatives were interviewed with the Five-Minute Speech Sample method. The relationships between EE and 3 clusters of patient-related variables (sociodemography, performance in cognitive tests, and psychopathology) were analyzed with stepwise regression analysis. With the exception of premorbid adjustment in childhood, only the cognitive variables were significantly associated with EE after controlling for the effect of the other variables. High EE was significantly associated with good performance in cognitive tests. Our results favor the attribution hypothesis of EE instead of the hypothesis that patient psychopathology would explain EE. Good cognitive functioning may lead to higher EE scores because of the higher expectations by the relatives.

Assessing expressed emotion: comparing Camberwell Family Interview and Five-minute Speech Sample ratings for mothers of children with behaviour problems

Little is known of the concordance between ratings of expressed emotion (EE) derived from the Camberwell Family Interview (CFI) and Five-minute Speech Sample (FMSS) for parents of children with behaviour problems. Concordance between CFI and FMSS ratings of EE was assessed prior to intervention and compared to parent-rated behaviour after intervention, at follow-up, 12 months later. Female primary caretakers of 75 children (3-10 years) showing behavioural difficulties were interviewed using FMSS and CFI. Interviews were coded independently by criterion-standard raters. Using CFI, 57 families were classified high EE, and 18 low EE. Using FMSS, 65 families were classified high EE and 10 low EE. 55/75 pairs of ratings (73%) were the same (high, n = 51: low, n = 4) and 20 mothers (27%) were allocated different EE status (Kappa = 0.14, n.s.). The FMSS ratings at initial interview appeared more closely related to behaviour rating at follow-up than CFI. Further investigation is required to establish comparability of CFI and FMSS results for carers of children.

Expressed emotion in relatives of first-episode and chronic patients with schizophrenia and major depressive disorder-a comparison

Relatives of first-episode and chronic schizophrenic and depressed patients were examined with respect to their expressed emotion (EE) status. The two aims of the study were to (1) investigate whether relatives of first-episode patients differed from family members of chronic patients, and (2) whether EE indices of relatives of schizophrenic patients were comparable to those of depressed subjects. Twenty patients of each diagnostic group (DSM-III-R and DSM-IV) were included, i.e. a total of 80 patients. The EE status of key relatives was assessed with the Five-Minute Speech Sample on the basis of critical comments and emotional overinvolvement. Additionally, the new criterion 'covert criticism' was applied to detect indirect expressions of critique. Relatives of first-episode and chronic patients of both diagnostic groups did not differ significantly regarding their EE status; in first-episode patients, 52.5% of relatives were classified high EE; in chronic patients, 45%. Moreover, EE indices of relatives of schizophrenic and depressed patients were comparable. Analysis revealed 52.5 and 45% high-EE relatives in the depression and the schizophrenia subsamples, respectively. Thus, the overall incidence of high-EE relatives was comparable to numbers reported in the literature. In our study EE status of relatives was not disease-specific, and it was independent of chronicity of illness.

The course of parental expressed emotion and psychotic episodes after family intervention in recent-onset schizophrenia. A longitudinal study

The stability of parental expressed emotion (EE) is analysed over about 9 years, and related to course of illness in patients with recent-onset schizophrenia. Families, who participated in a 15-month intervention, were randomised over two intervention conditions. Psychotic episodes were measured over 5 years after discharge. The Five Minute Speech Sample (FMSS) EE was elicited two times during the 12-month outpatient intervention and two times over 8 years after discharge on average. EE is expressed as criticism/dissatisfaction (CRIT), emotional overinvolvement (EOI), and as the classical dichotomous index. EE is not stable over the years. Intervention condition had no differential effect on EE as measured with CRIT and the dichotomous index. For EOI, an interaction between intervention condition and time was found. EE as assessed during intervention does not predict psychotic episodes during follow-up. An association was found between psychotic episodes and CRIT as assessed at 34 months after discharge. Family intervention may inhibit the development of high EOI for a limited period. Our results may be in support of the hypothesis that psychotic episodes in patients can affect the critical attitude in parents.

Expressed emotion

Expressed emotion (EE) refers to the quality of the emotional climate between a relative and a family member with a serious psychiatric disorder. Well-established, it has proven to be a reliable predictor of the relapse rate of psychiatric patients. In this article, the Camberwell Family Interview (CFI), the standard instrument, and 11 alternative EE measures will be presented and discussed with regard to their psychometric properties. It is concluded that the CFI remains the best instrument for assessing the quality of the relationship.
