Fear of childbirth measurement: appraisal of the content overlap of four instruments.

OBJECTIVE: To evaluate empirically the degree of content overlap between four self-report measures of fear of childbirth (FoC) identified as 'best in class' by a recent review. BACKGROUND: FoC and tokophobia is an area of increasing clinical concern and has been linked to poor maternal and neonatal outcomes. Clinical pathways have been established to improve care and interventions for FoC however, ambiguity and inconsistency remain regarding the most appropriate assessment measures. METHOD: A multi-rater and consensus content analysis was undertaken to determine the degree of overlap between four 'best in class' measures of FoC/tokophobia. RESULTS: The Slade-Pais expectations of childbirth scale (SPECS) was found to be the preferred measure in terms of symptom overlap of the tools evaluated, however, the overall level of overlap among these measures was weak. CONCLUSION: Limitations inherent to the current battery of preferred measures of FoC suggests both the desirability and urgency to develop a theoretically-grounded, psychometrically robust and accurate FoC assessment measure. Current measures of FoC are not interchangeable.

From classical psychodynamics to evidence synthesis: the motif of repression and a contemporary understanding of a key mediatory mechanism in psychosis.

The stress vulnerability model has proven to be a politically important model for two reasons. It has provided the framework that defines a temporal and dynamic process whereby a person's uniquely determined biopsychosocial vulnerability to schizophrenia symptoms interacts with his or her capacity to manage stress and the amount and type of stress experienced in such a way that the person experiences schizophrenia symptoms. Second, the development of this framework promoted the notion of inherited and acquired vulnerability. Implicit was that vulnerability was individually determined and that there was a role for psychosocial factors in the development/maintenance of schizophrenia symptoms. This proved to be a catalyst for the development of studies implicating psychosocial factors in the etiology of schizophrenia symptoms. Studies derived from cognitive-behavioral theories have proven the most successful in identifying thinking patterns, emotional disturbances, and neurocognitive and defensive vulnerability factors inherent in the development of schizophrenia symptoms. Historically, within the psychoanalytic school there has been debate regarding the role of repressive coping mechanisms in schizophrenia development. Psychoanalytic theories have always appeared incapable of providing etiologic explanations of schizophrenia symptoms, with the possible exception of Melanie Klein, than other more salient psychosocial schools. Mechanisms within the process of repressive coping are consistent with evidence and mechanisms supporting the stress vulnerability models and existing cognitive-behavioral theories regarding development of paranoid delusions. These mechanisms are less consistent with social cognitive explanations of schizophrenia symptoms.

The utility of the Illness Perception Questionnaire in the evaluation of mental health practitioners' perspectives on patients with schizophrenia.

UNLABELLED: RATIONALE, AIMS, OBJECTIVES: The Illness Perception Questionnaire (IPQ) was designed as a measure of illness perception and has been used extensively for measuring the perceptions of people with physical illness. Latterly modified versions of the IPQ have been used to measure the illness perceptions of people with mental health problems and their carers. This study examined the utility of a modified version of the IPQ to measure changes in mental health practitioners' illness perceptions about schizophrenia after undertaking psychosocial intervention training. METHOD: A total of 245 mental health practitioners who undertook psychosocial intervention training completed a modified version of the IPQ before and after training. The structure of the questionnaire was tested using confirmatory factor analysis. The internal consistency of sub-scales embedded in the instrument was also examined. RESULTS: The hypothesized structure failed to account for the data. Model fit indices revealed a poor fit to the data across all models evaluated. Cronbach's alpha revealed a number of sub-scales in the instrument to have mediocre internal consistency characteristics. CONCLUSIONS: The modified version of the IPQ is not suitable for evaluating the impact of psychosocial intervention training on changes in illness perceptions of schizophrenia in mental health practitioners. However, the study has highlighted the need to develop a valid and reliable measure to assess the illness perceptions health professionals have of patients in their care.
