Parent skills training treatment for parents of children and adolescents with eating disorders: a qualitative study

OBJECTIVE

This study examined the experience of parents of children with eating disorders after having participated in a skills-based training intervention.

METHOD

Eleven parents were interviewed and transcripts were analysed using inductive thematic analysis.

RESULTS

Parent responses were organised around key themes of (1) effectiveness and acceptability of the intervention; (2) interpersonal experience of the group process; and (3) feedback on intervention content. Overall, the transfer of specialist skills was highly valued by parents and applied within the home and hospital setting.

DISCUSSION

This study contributes preliminary evidence that skills-based training may improve parent self-efficacy,psychological distress, anxiety, and burden.This intervention can also be a cost-effective method for supporting carers,and future research is required to contribute data on treatment efficacy for patients in addition to parents.

A decade of data from a specialist statewide child and adolescent eating disorder service: does local service access correspond with the severity of medical and eating disorder symptoms at presentation?

BACKGROUND

Eating disorders affect up to 3% of children and adolescents, with recovery often requiring specialist treatment. A substantial literature has accrued suggesting that lower access to health care services, experienced by rural populations, has a staggering effect on health-related morbidity and mortality. The aim of this study was to evaluate whether lower service access foreshadowed a more severe medical and symptom presentation among children and adolescents presenting to a specialist eating disorders program.

METHOD

The data source was the Helping to Outline Paediatric Eating Disorders (HOPE) Project registry (N ~1000), a prospective ongoing registry study comprising consecutive paediatric tertiary eating disorder referrals. The sample consisted of 399 children and adolescents aged 8 to 16 years (M =14.49, 92% female) meeting criteria for a DSM-5 eating disorder.

RESULTS

Consistent with the hypotheses, lower service access was associated with a lower body mass index z-score and a higher likelihood of medical complications at intake assessment. Contrary to our hypothesis, eating pathology assessed at intake was associated with higher service access. No relationship was observed between service access and duration of illness or percentage of body weight lost.

CONCLUSIONS

Lower service access is associated with more severe malnutrition and medical complications at referral to a specialist eating disorder program. These findings have implications for service planning and provision for rural communities to equalize health outcomes.

Comparative study of children and adolescents referred for eating disorder treatment at a specialist tertiary setting

OBJECTIVE

To examine child and adolescent differences in the clinical presentation of eating disorders (EDs) at referral to a specialist pediatric program.

METHOD

This study compared cognitive, behavioral, and physical and medical features of children (≤ 12 years) and adolescents (13-18 years) with EDs presenting to a state-wide specialist pediatric ED service over two decades (N = 656; 8-18 years; 94% female).

RESULTS

Significant differences were found between the groups. Children were more commonly male (p < .001), had lower eating pathology scores (p < .001), were less likely to binge eat (p = .02), purge (p < .001) or exercise for shape and weight control (p < .001), and lost weight at a faster rate than adolescents (p = .009), whereas adolescents were more likely to present with bulimia nervosa spectrum disorders (p = .004). Children and adolescents did not differ significantly on mean body mass index z-score, percentage of body weight lost, or indicators of medical compromise (p > .05).

DISCUSSION

The clinical presentation of EDs differs among children and adolescents, with eating pathology and behavioral symptoms less prominent among children. Frontline health professionals require knowledge of these differences to assist with early detection, diagnosis, and prognosis.

Parent-child concordance in reporting of child eating disorder pathology as assessed by the eating disorder examination

OBJECTIVE

The aim of this study was to examine parent-youth concordance in reporting of eating disorder pathology, as assessed by the Eating Disorder Examination (EDE) in a clinical pediatric sample.

METHOD

The sample comprised 619 parent-youth dyads of youth (8-18 years) presenting for treatment at a specialist eating disorder clinic. A cross-sectional correlational design was used to examine the association between parent and youth symptom reports.

RESULTS

On the whole, parent-youth inter-rater agreement was poor to moderate. Agreement was acceptable for the presence of behavioral symptoms, with the exception of excessive exercise (PAK = 0.48-0.98). There was poor inter-rater agreement on frequency of behavioral symptoms, with parents providing lower estimates than youth (ICC = 0.07-0.52). Although we predicted that inter-rater agreement on cognitive symptoms would by higher with adolescents than children, both groups were discordant with parent reports. Younger children identified less severe eating disorder cognitions than parents and the opposite occurred for adolescents. An anorexia nervosa presentation and lower malnutrition were not associated with lower inter-rater agreement, as might have been expected through ego syntonicity. Youth with bulimia nervosa presentations reported significantly higher severity of cognitive symptoms and more frequent disordered eating behaviors compared with their parents.

DISCUSSION

Results support the utility of parent-youth assessment via the EDE to obtain a wider clinical picture of eating disorder psychopathology in children and adolescents, particularly for younger children. Clinical implications pertinent to administration of the EDE and parent literacy regarding eating disorder symptoms are discussed.

Psychotropic drug prescribing in an Australian specialist child and adolescent eating disorder service: a retrospective study

BACKGROUND

To describe the rates, indications, and adverse effects of psychotropic drug prescription in a specialist tertiary hospital child and adolescent eating disorder service.

METHODS

Retrospective case note study of all active eating disorder patients (N = 115) over the period of treatment from referral to time of study (M = 2 years), covering patient demographics, clinical characteristics, drug prescriptions, indications, and adverse effects.

RESULTS

Psychotropic drugs were prescribed in 45% of cases, most commonly antidepressants (41%), followed by anxiolytics (29%) and antipsychotics (22%), with 8% initiated before referral to the specialist eating disorder program. Common indications were depressed mood, agitation, anxiety, and insomnia. Patient clinical severity and complexity was associated with prescribing. Adverse effects, mostly minor, were recorded in 23% of antidepressant prescriptions, 39% of antipsychotic prescriptions, and 13% of anxiolytic prescriptions. Second generation antipsychotic prescription was associated with subsequent new onset binge eating, in this preliminary observational study. Self-harm by overdose of psychotropics occurred in 11% of patients prescribed medication.

CONCLUSIONS

Psychotropic medications were frequently prescribed to adolescent eating disorder patients to treat distressing symptoms. Prospective randomised controlled trials to clarify efficacy and safety are needed. Given the difficulties of conducting clinical trials in this population, services are encouraged to monitor and audit medication safety and efficacy in everyday practice, and to report their findings.

A hub and spokes approach to building community capacity for eating disorders in rural Western Australia

OBJECTIVE

To determine whether an outreach community-based training program on eating disorders enhances perceived capacity of rural health and education professionals to respond to and manage eating disorders.

DESIGN

Survey conducted upon completion of outreach training.

SETTING

Rural Western Australia.

PARTICIPANTS

Health and education professionals working in rural Western Australia.

MAIN OUTCOME MEASURES

Questionnaire responses analysed via descriptive statistics and inferential tests.

RESULTS

There was a significant increase in perceived ability to identify, support and/or treat people with eating disorders among health and education professionals.

CONCLUSIONS

Outreach training up-skilled rural gatekeepers and introduced systemic health system benefits of increased consultation and liaison, a fine-tuning of referral processes, a reduction in hospital admissions and better uptake of local services by patients discharged from hospital.

The HOPE (Helping to Outline Paediatric Eating Disorders) Project: development and debut of a paediatric clinical eating disorder registry

BACKGROUND

The HOPE (Helping to Outline Paediatric Eating Disorders) Project is an ongoing registry study made up of a sequential cross-sectional sample prospectively recruited over 17 years, and is designed to answer empirical questions about paediatric eating disorders. This paper introduces the HOPE Project, describes the registry sample to-date, and discusses future directions and challenges and accomplishments. The project and clinical service were established in a tertiary academic hospital in Western Australia in 1996 with a service development grant. Research processes were inbuilt into the initial protocols and data collection was maintained in the following years. Recognisable progress with the research agenda accelerated only when dedicated research resources were obtained. The registry sample consists of consecutive children and adolescents assessed at the eating disorder program from 1996 onward. Standardised multidisciplinary data collected from family intake interview, parent and child clinical interviews, medical review, parent, child and teacher psychometric assessments, and inpatient admission records populate the HOPE Project database.

RESULTS

The registry database to-date contains 941 assessments, of whom 685 met DSM-IV diagnostic criteria for an eating disorder at admission. The majority of the sample were females (91%) from metropolitan Perth (83%). The cases with eating disorders consist of eating disorders not otherwise specified (68%), anorexia nervosa (25%) and bulimia nervosa (7%). Among those with eating disorders, a history of weight loss since illness onset was almost universal (96%) with fear of weight gain (71%) common, and the median duration of illness was 8 months.

CONCLUSIONS

Over the next five years and more, we expect that the HOPE Project will make a strong scientific contribution to paediatric eating disorders research and will have important real-world applications to clinical practice and policy as the research unfolds.

Psychometric assessment of the Injection Pen Assessment Questionnaire (IPAQ): measuring ease of use and preference with injection pens for human growth hormone

Purpose

To examine the psychometric properties of the Injection Pen Assessment Questionnaire (IPAQ) including the following: 1) item and scale characteristics (e.g., frequencies, item distributions, and factor structure), 2) reliability, and 3) validity.

Methods

Focus groups and one-on-one dyad interviews guided the development of the IPAQ. The IPAQ was subsequently tested in 136 parent–child dyads in a Phase 3, 2-month, open-label, multicenter trial for a new Genotropin® disposable pen. Factor analysis was performed to inform the development of a scoring algorithm, and reliability and validity of the IPAQ were evaluated using the data from this two months study. Psychometric analyses were conducted separately for each injection pen.

Results

Confirmatory factor analysis provides evidence supporting a second order factor solution for four subscales and a total IPAQ score. These factor analysis results support the conceptual framework developed from previous qualitative research in patient dyads using the reusable pen. However, the IPAQ subscales did not consistently meet acceptable internal consistency reliability for some group level comparisons. Cronbach’s alphas for the total IPAQ score for both pens were 0.85, exceeding acceptable levels of reliability for group comparisons.

Conclusions

The total IPAQ score is a useful measure for evaluating ease of use and preference for injection pens in clinical trials among patient dyads receiving hGH. The psychometric properties of the individual subscales, mainly the lower internal consistency reliability of some of the subscales and the predictive validity findings, do not support the use of subscale scores alone as a primary endpoint.

Evaluating symptom outcomes in gastroparesis clinical trials: validity and responsiveness of the Gastroparesis Cardinal Symptom Index-Daily Diary (GCSI-DD)

BACKGROUND

Patient-reported symptom scales are needed to evaluate treatments for gastroparesis. The Gastroparesis Cardinal Symptom Index-Daily Diary (GCSI-DD) was developed to assess daily symptoms of gastroparesis. This study evaluated the validity and responsiveness of the GCSI-DD in patients with gastroparesis.

METHODS

Symptomatic patients were started with a new treatment for gastroparesis. Patients completed the GCSI-DD each evening during a baseline week and for 8 weeks of treatment. Responders were defined based on patient and clinician global rating of change. Minimal important differences (MID) were estimated based on baseline to 4 week changes in symptoms scores for small improvements.

KEY RESULTS

Of 69 patients participating, 46 had idiopathic, 19 diabetic, and four postfundoplication gastroparesis. Excellent test-retest reliability was seen for GCSI-DD scores, and there were significant correlations between GCSI-DD scores and clinician ratings of symptom severity. Responders to treatment reported improvements in nausea [effect size (ES) = 0.42, P < 0.001], postprandial fullness, ES = 0.83, P < 0.001), bloating (ES = 0.34, P < 0.001), early satiety (ES = 0.53, P < 0.001), but lower responses for upper abdominal pain (ES = 0.29), and vomiting (ES = 0.22; P = 0.119). MIDs were 0.55 for nausea, 0.97 for excessive fullness, 0.63 for bloating, 0.77 for postprandial fullness, and 0.30 for abdominal pain. A composite score of four symptoms (Composite-1; nausea, bloating, excessive fullness, postprandial fullness) had ES of 0.61 and MID of 0.73. Composite-2 score (nausea, early satiety, bloating, abdominal pain) had a lower ES of 0.47.

CONCLUSIONS & INFERENCES

Symptoms of early satiety, nausea, postprandial fullness, and bloating were responsive to treatment for gastroparesis. A composite of these symptoms also demonstrates validity and responsiveness to treatment for gastroparesis, and may represent an acceptable endpoint for evaluating the effectiveness of medical treatments in clinical trials for gastroparesis.

Does the Female Sexual Distress Scale-Revised cover the feelings of women with HSDD?

INTRODUCTION

Distress associated with low sexual desire is a key feature of hypoactive sexual desire disorder (HSDD). Accurate, reliable, and easy-to-use diagnostic tools to measure such distress are required. The Female Sexual Distress Scale-Revised (FSDS-R) has been shown to have good discriminant validity, test-retest reliability, and internal consistency in measuring sex-related personal distress in women with HSDD. However, the content validity (relevance, clarity, comprehensiveness) of the scale must also be established.

AIM

The aim of this study was to assess the content validity of the FSDS-R and to examine the potential of Item 13 as a stand-alone measure of distress associated with decreased sexual desire.

METHODS

A single-visit content validation study was conducted in three centers in the United States. Women were screened for HSDD; those with HSDD completed the FSDS-R and then underwent debriefing to capture information on their perceptions of the instrument. Participants also rated the relevancy of every FSDS-R item, from 0 ("not at all relevant") to 4 ("extremely relevant").

MAIN OUTCOME MEASURES

Female HSDD patients' ratings of the relevance and ease of understanding of the 13 items of the FSDS-R.

RESULTS

Twenty-five women with HSDD were interviewed. Mean relevancy ratings ranged from 1.96 (Item 9) to 3.33 (Item 13). Most participants (76-100%) found every item clear and easy to understand. Item 13 alone demonstrated good content validity, and 56% of participants felt that it covered all of their feelings about their low sexual desire.

CONCLUSIONS

This study established the content validity of the FSDS-R and demonstrated that the FSDS-R total score is a relevant endpoint for women with HSDD. The tool's one item specific to low sexual desire (Item 13) was given the highest score and highest relevancy of all items, and over half the sample felt that it covered all of their feelings about their low sexual desire.

Validation of the Revised Patient Perception of Migraine Questionnaire (PPMQ-R): Measuring Satisfaction with Acute Migraine Treatment in Clinical Trials

This study was aimed to evaluate in clinical trial settings the psychometric properties of the revised Patient Perception of Migraine Questionnaire (PPMQR), a satisfaction measure for acute migraine treatment. The PPMQ-R was administered 24 h post dosing in 1304 migraineurs randomized to two identical Phase 3, single-attack trials. Reliability, concurrent and construct validity and known-groups validity were evaluated using Cronbach's α, Pearson correlations and analysis of variance, respectively. PPMQ-R scale and Total scores (Efficacy, Functionality and Ease of use) showed very good internal consistency reliability (α 0.84-0.99). Efficacy, Functionality and Total PPMQ-R scores showed large, inverse relationships with migraine pain severity, number of migraine symptoms and work ability ( r = −0.62 to −0.75; all P < 0.0001). All scales discriminated among migraine pain severity levels (all P < 0.001). The PPMQ-R has sufficient evidence of validity and reliability for measuring patient satisfaction, an important benchmark of quality and effective care.

Daily versus weekly azithromycin in cystic fibrosis patients

Four randomised, placebo-controlled trials have previously documented the clinical benefits of azithromycin (AZM) in cystic fibrosis (CF) patients. The present study examined whether the beneficial effect of AZM is equivalent when administered daily or weekly. A double-blind, randomised study was carried out in 208 CF patients aged 6-58 yrs who were assigned to AZM either 250 mg daily (n = 103) or 1,200 mg weekly (n = 105) for 6 months, with assessments at baseline and at 1, 3, 6 and 7 months. Patients were taken from five adult and children CF centres in South-east Queensland, Australia. Equivalence was demonstrated between the two groups (daily versus weekly) with respect to improvements in lung function (forced expiratory volume in one second and forced vital capacity), C-reactive protein, days spent in hospital, admission rates and nutrition (body mass index, z-scores) using 95% confidence intervals with a tolerance interval of +/-10%. In patients aged <18 yrs the daily group had significantly better improvements in z-scores for height and weight after 6 months. In children, a nutritional advantage for daily administration was found. Gastro-intestinal adverse effects were more common with weekly therapy. Apart from these findings, daily and weekly administered azithromycin demonstrated similar outcomes for cystic fibrosis patients.

Non-eating disorders psychopathology in children and adolescents with eating disorders: implications for malnutrition and symptom severity

OBJECTIVES

To compare the general psychopathology in an eating disorders (ED) and a child mental health outpatient sample and investigate the implications of comorbidity on psychological and physical measures of ED severity.

METHODS

One hundred thirty-six children and adolescents with a DSM-IV ED diagnosis were compared with age- and gender-matched controls. Measures included the Eating Disorders Examination and the Child Behavior Checklist.

RESULTS

The ED group had lower general and externalizing psychopathology scores and no difference in internalizing (anxiety-depression) symptoms. Of the anorexia nervosa group, 49% experienced comorbid psychopathology. This group had significantly higher ED psychopathology, longer duration of illness, and more gastrointestinal symptoms, but no difference in malnutrition status. Eating disorders not otherwise specified (EDNos) group measures were less influenced by comorbidity status.

CONCLUSIONS

Anxiety-depressive symptoms are very common in children and adolescents with EDs. Comorbidity status influences illness severity, especially in the anorexia nervosa group. The management implications of these findings are discussed.

Letting the family know: balancing ethics and effectiveness when notifying relatives about genetic testing for a familial disorder

OBJECTIVE

To increase the awareness among at risk relatives of the availability of genetic testing for a familial disorder while respecting their autonomy and privacy.

METHODS

This was a comparison of preintervention and postintervention cohorts of families carried out in a state wide clinical service providing genetic counselling and testing for people at risk of familial adult onset cancer. Unaffected relatives who were not clients of the service in 74 kindreds with familial mutations causing familial breast and ovarian cancer, hereditary non-polyposis colorectal cancer, or Cowden syndrome were included in the study. In the baseline cohort (41 kindreds), family members who were clients of the clinical service and had been shown to be carriers of mutations were asked to advise relatives that genetic testing was available. In the intervention cohort (33 kindreds), the clinical service obtained consent to advise at risk relatives by letter that genetic testing was available. The main outcome measures were: (a) proportion of unaffected first and second degree relatives of the proband in each family whose genetic status was clarified within 2 years of the mutation being identified in the family, and (b) concerns regarding privacy and autonomy voiced by relatives receiving these letters.

RESULTS

In the baseline cohort, the average proportion of relatives in each family whose genetic status was clarified was 23%. In the intervention cohort, the average proportion of relatives in each family whose genetic status was clarified was 40% (p = 0.001). None of the relatives in the intervention cohort complained of a breach of privacy or autonomy.

CONCLUSION

Clinical services can take an effective and proactive approach to notifying relatives who are not their clients of the availability of genetic testing without compromising principles of privacy and autonomy.

Comparison of contamination rates of catheter-drawn and peripheral blood cultures

The aim of this study was to assess the sensitivity and specificity of catheter-drawn and peripheral blood cultures. Paired blood culture samples collected over a 44-month period from a 280 bed Brisbane metropolitan hospital were analysed, using standard clinical and microbiological criteria, to determine whether blood culture isolates represented true bacteraemias or contamination. Catheter-collected cultures had a specificity of 85% compared with 97% for peripheral cultures. In only two instances (0.2%) was the diagnosis of clinically significant bacteraemia made on the basis of catheter culture alone. This study concluded that catheter-collected samples are not a good test for true bacteraemia, and that peripheral cultures are more reliable when the results of the paired cultures are discordant.
