The stability of the Parental Bonding Instrument over a 20-year period

BACKGROUND The Parental Bonding Instrument (PBI) measures the perception of being parented to the age of 16 years. Low scores on the care dimension and high scores on the overprotection dimension are considered to be risk factors of depression. While the PBI has been shown to be a reliable and valid instrument, the stability of the PBI over extended periods (taking into account individual characteristics and life experience) needs to be demonstrated. METHOD The PBI was measured in a non-clinical cohort on four waves between 1978 and 1998, along with a series of self-report measures including state depression and neuroticism. Differences in PBI change over time were examined by gender, lifetime major depression diagnosis, and life event variables, as well as by scores on neuroticism and state depression. RESULTS Acceptable retest coefficients on PBI scores over the 20-year study were found for the cohort. No differences were found in PBI scores over time on the variables examined, including sex and depression measures. CONCLUSIONS The results indicate long-term stability of the PBI over time. The influences of mood state and life experience appear to have little effect on the stability of the perception of parenting as measured by the PBI. The present study increases confidence in the PBI as a valid measure of perceived parenting over extended time periods.

Longitudinal study of outcome of chronic fatigue syndrome

Abstract Objective : To examine the predictors of long term outcome for patients with the chronic fatigue syndrome. Design : Cohort study. Subjects : 139 subjects previously enrolled in two treatment trials; 103 (74%) were reassessed a mean of 3.2 years after start of the trials. Setting : University hospital referral centre. Main outcome measures : Age at onset, duration of illness, psychological and immunological status at initial assessment. Ongoing symptom severity, levels of disability, and immunological function at follow up. Results - 65 subjects had improved but only six reported no current symptoms. An alternative medical diagnosis had been made in two and psychiatric illness diagnosed in 20. The assignment of a primary psychiatric diagnosis at follow up and the strength of the belief that a physical disease process explained all symptoms at entry to the trials both predicted poor outcome. Age at onset of illness, duration of illness, neuroticism, premorbid psychiatric diagnoses, and cell mediated immune function did not predict outcome. Conclusion : Though most patients with the chronic fatigue syndrome improve, a substantial proportion remain functionally impaired. Psychological factors such as illness attitudes and coping style seem more important predictors of long term outcome than immunological or demographic variables.

Psychosocial effects on carers of living with persons with dementia.

A survey of members of the Alzheimers Disease and Related Disorders Society confirmed high rates of psychological morbidity, though not of depression, and social isolation in family carers of persons with dementia. Psychological morbidity in carers was associated with having an affected person at home, the carer being a spouse, demanding problem behaviours, poor physical health in the carer, social isolation, dissatisfaction with social supports, greater use of psychotropic medication, and a deteriorated marital relationship. Carers and patients had high rates of consultations with doctors and other health professionals. There was a vulnerable group of carers who were impaired psychologically, socially and physically. The identification of risk factors to carer morbidity may lead to useful interventions.

The development of a refined measure of dysfunctional parenting and assessment of its relevance in patients with affective disorders

BACKGROUND The Parental Bonding Instrument (PBI) measures fundamental parenting dimensions (care and over-protection), but does not directly assess abusive parenting. METHODS We describe the development of the Measure of Parenting Style (the MOPS), comprising refined PBI scales assessing parental indifference and over-control, as well as a scale assessing parental abuse. RESULTS We examine psychometric properties of the MOPS, while several analyses build to the concurrent validity of the abuse scale as an experimental measure. We examine the extent to which both the PBI and the MOPS scales showed specificity of dysfunctional parenting to the non-melancholic depressive subtype, and across a range of anxiety disorders. Non-melancholic depressed patients returned anomalous parenting scale scores (compared to melancholic subjects), but only when such subtyping decisions were clinician-generated. Those receiving DSM-III-R lifetime anxiety diagnoses of panic disorder and of social phobia returned higher PBI protection and MOPS over-control scores than non-anxious subjects, while differences were not established for those with generalized anxiety disorder or obsessive compulsive disorder. CONCLUSIONS We consider the likely utility of the MOPS scale and note the module capacity of separate MOPS and PBI scales, which allow a set of options for assessing perceived parenting characteristics.

Low parental care as a risk factor to lifetime depression in a community sample.

A number of studies have reported links between experiencing low parental care and subsequent depressive experience. As the majority have involved patient samples, links may reflect anomalous parenting disposing to help-seeking behaviour (and patient status) rather than directly to depression. We, therefore, report a community study, so redressing any such artefact emerging from a patient sample and, additionally, quantify the relevance of low parental care to depression in comparison to several other risk factors (i.e., age, gender, educational level, socioeconomic status and marital status). Subjects were drawn from the ECA study and comprised those assessed at the 1-year follow-up interview undertaken at the New Haven site, with parental care being assessed by a key item from the Parental Bonding Instrument (PBI). Those reaching criteria for a lifetime episode of major depressive disorder were significantly more likely to report low care from both parents as well as to be female, divorced or separated, and younger. Low parental care (along with age and mental status but not female sex) appeared pathoplastic in being linked with an increased chance of psychopathology in general, rather than demonstrating specificity to major depressive disorder.

Can the chronic fatigue syndrome be defined by distinct clinical features

To determine whether patients diagnosed as having chronic fatigue syndrome (CFS) constitute a clinically homogeneous class, multivariate statistical analyses were used to derive symptom patterns and potential patient subclasses in 565 patients. The notion that patients currently diagnosed as having CFS constitute a single homogeneous class was rejected. An alternative set of clinical subgroups was derived. The validity of these subgroups was assessed by sociodemographic, psychiatric, immunological and illness behaviour variables. A two-class statistical solution was considered most coherent, with patients from the smaller class (27% of the sample) having clinical characteristics suggestive of somatoform disorders. The larger class (73% of sample) presented a more limited combination of fatigue and neuropsychological symptoms, and only moderate disability but remained heterogeneous clinically. The two patient groups differed with regard to duration of illness, spontaneous recovery, severity of current psychological morbidity, utilization of medical services and CD8 T cell subset counts. The distribution of symptoms among patients was not unimodal, supporting the notion that differences between the proposed subclasses were not due simply to differences in symptom severity. This study demonstrated clinical heterogeneity among patients currently diagnosed as CFS, suggesting aetiological heterogeneity. In the absence of discriminative clinical features, current consensus criteria do not necessarily reduce the heterogeneity of patients recruited to CFS research studies.

Psychotic (delusional) depression: a meta-analysis of physical treatments.

Literature reviews have suggested that combination antidepressant/antipsychotic drug therapy and electroconvulsive therapy (ECT) are of comparable efficacy in treating psychotic depression, and distinctly superior to antidepressant alone or antipsychotic alone. We undertook a meta-analysis of 44 studies, and focussed on those three principal treatment options. There was a trend for ECT to be superior to combination drug therapy, with bilateral ECT being suggested as distinctly more effective than unilateral, and ECT was demonstrated to be significantly superior to tricyclic drug alone. Combination drug therapy ranked as more effective than antipsychotic alone and than antidepressant alone, but that greater efficacy was not significant.

It's Now or Never: Fertility-Related Knowledge, Decision-Making Preferences, and Treatment Intentions in Young Women With Breast Cancer—An Australian Fertility Decision Aid Collaborative Group Study

PURPOSE For many young women with early breast cancer, fertility is a priority. Interventions to retain fertility options generally need to be accessed before chemotherapy, but many women do not receive information regarding these options in a timely fashion. Knowledge about fertility and decisional conflict has not previously been measured in young patients with breast cancer considering future pregnancies. METHODS One hundred eleven young women with early breast cancer who had not yet completed their families were recruited around the time of diagnosis. Knowledge regarding fertility-related information, decisional conflict, and preferences regarding fertility information and decision making was measured. RESULTS From a potential fertility-related knowledge score of 10, the mean was 5.2 (standard deviation = 2.3; range, 0 to 10). Decreased knowledge was associated with increased decisional conflict about pursuing fertility preserving interventions (odds ratio [OR] = 0.57; 95% CI, 0.44 to 0.73; P < .001). Thirty-one percent of women reported that they would consider undertaking in vitro fertilization (IVF) as a method to conserve their fertility, whereas 38% were uncertain. Consideration of IVF was not related to whether subjects were in a committed relationship (OR = 1.20; P = .716) or a definite desire for more children (OR = 1.54; P = .513). CONCLUSION Around diagnosis, many young patients with breast cancer have low levels of knowledge about fertility issues. Further, low knowledge is associated with increased decisional conflict, which is likely to undermine the quality of decision making. These findings suggest that targeted and timely fertility information may reduce decisional conflict and increase informed choice. Neither relationship status nor firm plans regarding future children reliably predict desire to pursue fertility preservation.

Impact of a mobile phone and web program on symptom and functional outcomes for people with mild-to-moderate depression, anxiety and stress: a randomised controlled trial.

BackgroundMobile phone-based psychological interventions enable real time self-monitoring and self-management, and large-scale dissemination. However, few studies have focussed on mild-to-moderate symptoms where public health need is greatest, and none have targeted work and social functioning. This study reports outcomes of a CONSORT-compliant randomised controlled trial (RCT) to evaluate the efficacy of myCompass, a self-guided psychological treatment delivered via mobile phone and computer, designed to reduce mild-to-moderate depression, anxiety and stress, and improve work and social functioning.MethodCommunity-based volunteers with mild-to-moderate depression, anxiety and/or stress (N = 720) were randomly assigned to the myCompass program, an attention control intervention, or to a waitlist condition for seven weeks. The interventions were fully automated, without any human input or guidance. Participants’ symptoms and functioning were assessed at baseline, post-intervention and 3-month follow-up, using the Depression, Anxiety and Stress Scale and the Work and Social Adjustment Scale.ResultsRetention rates at post-intervention and follow-up for the study sample were 72.1% (n = 449) and 48.6% (n = 350) respectively. The myCompass group showed significantly greater improvement in symptoms of depression, anxiety and stress and in work and social functioning relative to both control conditions at the end of the 7-week intervention phase (between-group effect sizes ranged from d = .22 to d = .55 based on the observed means). Symptom scores remained at near normal levels at 3-month follow-up. Participants in the attention control condition showed gradual symptom improvement during the post-intervention phase and their scores did not differ from the myCompass group at 3-month follow-up.ConclusionsThe myCompass program is an effective public health program, facilitating rapid improvements in symptoms and in work and social functioning for individuals with mild-to-moderate mental health problems.Trial registrationAustralian New Zealand Clinical Trials Registry ACTRN 12610000625077

What is chronic fatigue syndrome? Heterogeneity within an international multicentre study

Objective: We sought to compare the characteristics of patients presenting with chronic fatigue (CF) and related syndromes in eight international centres and to subclassify these subjects based on symptom profiles. The validity of the subclasses was then tested against clinical data. Method: Subjects with a clinical diagnosis of CF completed a 119-item self-report questionnaire to provide clinical symptom data and other information such as illness course and functional impairment. Subclasses were generated using a principal components-like analysis followed by latent profile analysis (LPA). Results: 744 subjects returned complete data sets (mean age 40.8 years, mean length of illness 7.9 years, female to male ratio 3:1). Overall, the subjects had a high rate of reporting typical CF symptoms (fatigue, neuropsychological dysfunction, sleep disturbance). Using LPA, two subclasses were generated. Class one (68% sample) was characterized by: younger age, lower female to male ratio; shorter episode duration; less premorbid, current and familial psychiatric morbidity; and, less functional disability. Class two subjects (32%) had features more consistent with a somatoform illness. There was substantial variation in subclass prevalences between the study centres (Class two range 6–48%). Conclusions: Criteria-based approaches to the diagnosis of CF and related syndromes do not select a homogeneous patient group. While substratification of patients is essential for further aetiological and treatment research, the basis for allocating such subcategories remains controversial.
