Questionnaire screening for mental health problems in Bangladeshi children: a preliminary study

  Background: In the developing world, child psychiatric disorders are common but child mental health professionals are scarce. A cheap and effective method for detecting child psychiatric problems would be useful. The present study examined the potential suitability of the Strengths and Difficulties Questionnaire (SDQ) for this role. Methods: SDQs were administered to the parents and teachers of 261 Bangladeshi 4–16 year olds: 99 drawn from a psychiatric clinic and 162 drawn from the community. Self-report SDQs were completed by 11–16 year olds. Children from the clinic sample were assigned psychiatric diagnoses blind to their SDQ scores. Results: SDQ scores distinguished well between community and clinic samples, and also between children with different psychiatric diagnoses in the clinic sample. A simple algorithm based on SDQ scores was used to predict whether children had hyperkinesis, conduct disorders, emotional disorders or any psychiatric disorder – rates of predicted disorder varied markedly between clinic and community samples. Conclusions: Predictions based on multi-informant SDQs potentially provide a cheap and easy method for detecting children in the developing world with significant mental health problems. The potential effectiveness of any such screening programme should be evaluated on a broad range of children, using both international and culture-specific assessments.

Prevalence of emotional and behavioural problems among 6–12 year old children in Egypt

Epidemiological information about prevalence of child mental health problems is essential to inform policy and public health practice. This information is weak in many developing countries and those in developmental transition. There have been few such studies in Arab countries and none in Egypt. We conducted a population prevalence study of emotional and behavioural disorders among 1186 6–12 year old children in Minia, Egypt. Data was collected from teachers and parents using the Strengths and Difficulties Questionnaire with a 98 and 91% response respectively. Prevalence of abnormal symptom scores is reported for both parents and teachers. Prevalence of probable psychiatric diagnoses was measured using the SDQ multi-informant algorithm. These prevalences have then been compared to published UK data. The prevalence of emotional and behavioural symptoms was high as reported by both parents and teachers (Abnormal total difficulties: teachers 34.7% (95% CI 32.0–37.5), parents 20.6% (18.2–23.2). Abnormal prosocial scores: teachers 24.9% (22.5–27.5), parents 11.8% (9.9–13.9)) but prevalence of probable psychiatric diagnoses was much lower (Any psychiatric diagnosis 8.5% (6.9–10.5); Emotional disorder 2.0% (1.2–3.0); Conduct disorder 6.6% (5.1–8.3); Hyperactivity disorder 0.7% (0.3–1.4)). Comparison with UK data showed higher rates of symptoms but similar rates of probable disorders. Despite public, professional and political underestimation of child mental health problems in Egypt, rates of symptoms are higher than in developed countries, and rates of disorders are comparable. These findings support greater investment in community and primary care prevention and treatment initiatives.     

Comparing psychiatric diagnoses generated by the Strengths and Difficulties Questionnaire with diagnoses made by clinicians

OBJECTIVE: To examine the level of agreement between clinical diagnoses by a community child and adolescent mental health service (CAMHS) and diagnoses generated by the Strengths and Difficulties Questionnaire (SDQ). METHOD: A computerized algorithm developed by Goodman et al. was used at a community CAMHS in Australia to predict child psychiatric diagnoses on the basis of the symptom and impact scores derived from the SDQ completed by parents (n = 130), teachers (n = 101) and young people (n = 38). These diagnoses were compared with the diagnoses made by clinicians in a multidisciplinary community outpatient team and an independent clinician that examined the case notes and was blind to the SDQ scores. RESULTS: The level of agreement between SDQ generated diagnoses and clinical team diagnoses was moderate to high, ranging from 0.39 to 0.56. Correlations between the SDQ and an independent clinician ranged from 0.26 to 0.43. All were statistically significant. CONCLUSION: The SDQ is a useful instrument to aid clinicians in diagnosis and could be used as part of the initial assessment process.     

Mental health in pediatric settings: distribution of disorders and factors related to service use

OBJECTIVES: To examine child psychiatric disorders in pediatric settings and identify factors associated with parents' use of pediatricians as resources concerning emotional/behavioral issues and use of mental health services. METHOD: The sample consists of 5- to 9-year-olds (mean = 7.17 years, SD = 1.41) from a representative sample (N = 1,060) of pediatric practices. Parent interviews included assessments of psychiatric disorders with the Diagnostic Interview Schedule for Children (DISC-R), parental depression/anxiety, possible child abuse, stress, support, and the use of mental health services. RESULTS: The prevalence of any DISC disorder was 16.8%. Parental depression/anxiety and possible child abuse were associated independently with 2- to 3-times higher rates of disorder. Many parents (55%) who reported any disorder did not report discussing behavioral/emotional concerns with their pediatrician. Factors associated with discussing behavioral/emotional issues were the presence of any disorder and financial stress. Factors related to seeing a mental health professional were discussing behavioral/emotional issues with the pediatrician, single parenthood, and stressful life events. CONCLUSIONS: The prevalence rates of disorders in this setting suggest that pediatricians are well-placed to identify and refer children with psychiatric disorders. However, most parents do not discuss behavioral/emotional issues with their pediatrician. Methods for improving rates of identification and referral (e.g., routine screening) are considered.     

The prevalence of psychiatric disorders among 5–10 year olds in rural, urban and slum areas in Bangladesh

BACKGROUND: No previous epidemiological studies of child mental health have been conducted in Bangladesh, partly due to lack of suitable measures. METHODS: A Bangla translation of a standardised child psychiatric interview, the Development and Well-Being Assessment (DAWBA), was validated against routine clinical diagnoses on a consecutive series of 100 referrals to a child mental health service. A two-phase study of prevalence was applied to random samples of 5- to 10-year-olds (N=922) drawn from three contrasting areas: a rural area, a moderately prosperous urban area, and an urban slum. RESULTS: There was substantial agreement between the DAWBA and the independent clinic diagnosis (kappa=0.63-0.94). The estimated prevalence of any ICD-10 diagnosis was 15% (95% CI 11-21%). The rate of obsessive-compulsive disorder was higher than in previous studies. Children from the slum area were significantly more likely to have serious behavioural problems, and marginally more likely to have post-traumatic stress disorder. CONCLUSION: A conservative extrapolation is that around 5 million Bangladeshi children and adolescents have psychiatric disorders. In a country with very few child mental health professionals, there is a vast gap between need and provision that must be addressed.     

Importance of clinical diagnoses for comorbidity studies in substance use disorders

Many clinical and epidemiologic studies have shown a high frequency of co-occurrence of substance abuse and psychiatric disorders, with important consequences from health and social perspective. However, the identification of reliable and valid diagnosis of psychiatric comorbidity in substance abusers is problematic, mainly because the acute or chronic effects of substance abuse can mimic symptoms of many other mental disorders, making difficult to differentiate psychiatric symptoms that represent effects of acute or chronic substance use or withdrawal, of those that represent an independent disorder. While DSM-IIII-R and earlier nomenclatures were unclear in differentiating independent from other psychiatric disorders, DSM-IV and DSM-IV-TR provided clearer guidelines in diagnosing psychiatric disorders in heavy users of alcohol and drugs, providing three categories: "primary" psychiatric disorders, "substance-induced" disorders, and "expected effects" of the substances, meaning expected intoxication and/or withdrawal symptoms that should not be diagnosed as symptoms of a psychiatric disorder. The use of the "Psychiatric Research Interview for Substance and Mental Disorders (PRISM)", a structured interview developed to improve the diagnosis of co morbidity in drug abusers according DSM-IV, supplies new opportunities in the clinical research in this field.     

Strengths and Difficulties Questionnaire as a Dimensional Measure of Child Mental Health

ObjectiveTo provide the first explicit evaluation of the dimensionality of the total difficulties score of the Strengths and Difficulties Questionnaire (SDQ), a widely used measure of child mental health. We do so by validating the SDQ across its full range against the prevalence of clinical disorder.MethodWe use two large (n = 18,415) nationally-representative surveys of children and adolescents aged 5 to 16 years in the general British population. Strengths and Difficulties Questionnaires were completed separately by parents, teachers, and children aged 11 to 16 years, and children also received a multi-informant clinician-rated clinical diagnosis. Approximately 7,912 children from the baseline survey were also reassessed for clinical diagnosis at 3-year follow-up.ResultsAcross the full range of the parent, teacher, and youth SDQ, children with higher total difficulty scores have greater psychopathology as judged by the prevalence of clinical disorder. This was true cross-sectionally and also in predicting to disorder status 3 years later. There was no evidence of threshold effects for the SDQ at either high or low scores, but rather the odds of disorder increased at a constant rate across the range (odds ratios between 1.14 and 1.28 per 1-point increase in SDQ score).ConclusionsOur findings support the use of the SDQ as a genuinely dimensional measure of child mental health.     

Should Clinicians Split or Lump Psychiatric Symptoms? The Structure of Psychopathology in Two Large Pediatric Clinical Samples from England and Norway

It has been suggested that the structure of psychiatric phenomena can be reduced to a few symptom dimensions. These proposals, mainly based on epidemiological samples, may not apply to clinical populations. We tested the structure of psychiatric symptoms across two pediatric clinical samples from England (N?=?8434) and Norway (N?=?5866). Confirmatory factor analyses of the parent-reported Strengths and Difficulties Questionnaire (SDQ) evaluated the relative fit of several models, including a first-order model, a second-order model with the widely-established broad symptom dimensions of internalizing-externalizing, and two bi-factor models capturing a general psychopathology factor. Predictive value of the SDQ subscales for psychiatric disorders was examined. A first-order five-factor solution better fit the data. The expected SDQ subscale(s) related best to the corresponding psychiatric diagnosis. In pediatric clinical samples, a granular approach to psychiatric symptoms where several dimensions are considered seems to fit the data better than models based on lumping symptoms into internalizing/externalizing dimensions.     

Quality of life in children with psychiatric disorders: self-, parent, and clinician report

OBJECTIVE: To study the relationship between child psychiatric disorders and quality of life (QoL). METHOD: In a sample of 310 children (ages 6-18 years) referred for psychiatric problems, children, parents, and clinicians reported on psychopathology and subjective and objective QoL indicators. RESULTS: Six diagnostic categories were distinguished: attention-deficit and disruptive behavior disorders, anxiety disorders, pervasive developmental disorders, mood disorders, other disorders, and no diagnosis. In overall QoL, no differences were found between the diagnostic categories, except in clinician's ratings, who rated children with pervasive developmental disorder as having a poorer QoL than children with other diagnoses. In each diagnostic category specific QoL subdomains were affected: for children with attention-deficit and disruptive behavior disorder, school functioning and social functioning; for children with anxiety disorder, emotional functioning; for children with pervasive developmental disorder, social functioning; and for children with mood disorder, emotional functioning. CONCLUSIONS: Across multiple raters, the distinguished child psychiatric disorders had a different impact on QoL. Knowledge about domains of QoL that are affected in specific child psychiatric disorders can help clinicians to focus on particular QoL domains during the diagnostic process and to define adequate treatment goals.     

Uncommon troubles in young people: prevalence estimates of selected psychiatric disorders in a nonreferred adolescent population

A two-stage epidemiologic strategy was used to estimate the lifetime prevalence of selected DSM-III-defined psychiatric disorders in a county-wide secondary school population (N = 5596). Screening tests used in the first stage included items based on DSM-III criteria for eating disorders and panic disorder, as well as the Leyton Obsessional Inventory-Child Version and the Beck Depression Inventory. Based on interviews (n = 356) by clinicians in the second stage, the lifetime prevalence of anorexia nervosa was 0.2%; bulimia, 2.5%; panic disorder, 0.6%; obsessive-compulsive disorder, 1.9%; major depression, 4.0%; dysthymic disorder, 4.9%; and generalized anxiety disorder, 3.7%. While rates of mental health service utilization varied greatly by diagnosis, only 41% of students who were assigned both a diagnosis and a rating of impairment had received any kind of clinical attention.     

Psychiatric disorder prevalence among deaf and hard-of-hearing outpatients

Objectives

To contribute to the dearth of literature on the prevalence rates of psychiatric disorders in deaf adults, this study examined the diagnostic and clinical characteristics of deaf psychiatric outpatients in comparison to hearing psychiatric outpatients.

Methods

Archival clinical data for deaf adults (N=241), treated at a specialized, linguistically and culturally affirmative outpatient community mental health program from 2002 to 2010, was compared to data from a random sample of hearing adult outpatients (N=345) who were treated at the same community mental health center.

Results

In various diagnostic categories, significant differences were seen between the deaf and hearing groups: bipolar disorders (3.7% versus 14.2%), impulse control disorders (15.8% versus 5.2%), anxiety disorders (18.7% versus 30.1%), attention deficit hyperactivity disorder (11.2% versus 4.9%), pervasive developmental disorders (3.3% versus 0.3%), substance use disorders (27.8% versus 48.4%), and intellectual disabilities (10.4% versus 2.9%).

Conclusions

The deaf outpatient group evidenced a different diagnostic profile than the hearing sample. It is suggested that the use of culturally competent and fluent ASL-signing clinicians provides more diagnostic clarity and is encouraged as a best practice for the care of deaf individuals.     

Comorbidity in the interpretation of dexamethasone suppression test results in children: a review and report

The dexamethasone suppression test (DST) was administered as part of the initial clinical assessment to 83 children and adolescents who were consecutively referred for outpatient evaluation. All diagnoses were made clinically by a child psychiatrist according to DSM-III criteria. A weight-corrected dose of dexamethasone of 17 micrograms/kg was used. DSM-III diagnoses were made independent of DST results. Patients were stratified into four main diagnostic groups: major depressive disorder (MDD) (N = 27); attention deficit disorder with hyperactivity (ADDH) (N = 22); major depressive disorder plus attention deficit disorder with hyperactivity (MDD + ADDH) (N = 29); and psychiatric controls (PC) (N = 5). Rates of dexamethasone nonsuppression were found to be similarly elevated in children with MDD (29.6%), ADDH (22.7%), and MDD + ADDH (37.9%). All 5 psychiatric control patients had a normal postdexamethasone suppression (0%). A similar pattern of results emerged in a reexamination of the literature on available studies of DST in juveniles which revealed that children with major affective disorders, attention deficit disorder (ADDH), and anxiety disorders had comparable DST results that were significantly higher than the 5.6% rate found in normal controls. These findings provide further support for similarities in DST results between ADDH and MDD in outpatients. Although these results suggest a lack of specificity of the DST as a laboratory aid for the diagnosis of juvenile affective disorders, they are also consistent with findings indicating that the DST may be an index of clinical severity and other findings suggesting a possible association between ADDH and MDD. Despite its limitations, the DST may provide potentially useful clinical and research information regarding the pathophysiology of psychiatric disorders and in alerting clinicians to the presence of serious psychiatric disorders. The findings also stress the relevance of assessing comorbidity in interpreting DST results.     

Depression and anxiety among mothers who bring their children to a pediatric mental health clinic

OBJECTIVE: Maternal psychiatric illness is a potent risk factor for child psychiatric disorders, but little is known about rates of psychiatric diagnoses among mothers who bring their children to pediatric mental health clinics. This study investigated rates of psychiatric disorders among mothers of children presenting for psychiatric evaluation and examined the relationship between maternal diagnosis and child psychopathology. METHODS: Interviewers conducted structured diagnostic interviews with nonpsychotic, school-age children and their mothers (N=222) and collected self-report measures of symptoms, functioning, and social support. RESULTS: One-hundred-thirty-five participating mothers (61 percent) met DSM-IV criteria for a current axis I disorder, most commonly depression (35 percent) and anxiety (42 percent). Children of mothers with a diagnosis met criteria for significantly more diagnoses on the Schedule for Affective Disorders and Schizophrenia for School Age Children, Present and Lifetime version and had significantly higher scores on measures of internalizing and externalizing symptoms than children of mothers without a diagnosis. Two-thirds of mothers with a diagnosis were not receiving psychiatric treatment. CONCLUSIONS: More than half the mothers who brought their children for psychiatric treatment were themselves suffering from a psychiatric disorder. Maternal psychiatric illness was, in turn, associated with greater occurrence of psychopathology among offspring, underscoring the importance of developing interventions that address the needs of both children with psychiatric disorders and their at-risk mothers.     

Psychiatric comorbidity,family dysfunction,and social impairment in referred youth with oppositional defiant disorder

OBJECTIVE: The authors sought to achieve an improved understanding of the diagnosis of oppositional defiant disorder independent of its association with conduct disorder. METHOD: Family interactions, social functioning, and psychiatric comorbidity were compared in clinically referred male and female subjects with oppositional defiant disorder alone (N=643) or with comorbid conduct disorder (N=262) and a psychiatric comparison group with neither oppositional defiant disorder nor conduct disorder (N=695). RESULTS: Oppositional defiant disorder youth with or without conduct disorder were found to have significantly higher rates of comorbid psychiatric disorders and significantly greater family and social dysfunction relative to psychiatric comparison subjects. Differences between subjects with oppositional defiant disorder alone and those with comorbid conduct disorder were seen primarily in rates of mood disorders and social impairment. Oppositional defiant disorder was a significant correlate of adverse family and social outcomes when comorbid disorders (including conduct disorder) were controlled. CONCLUSIONS: These results support the validity of the oppositional defiant disorder diagnosis as a meaningful clinical entity independent of conduct disorder and highlight the extremely detrimental effects of oppositional defiant disorder on multiple domains of functioning in children and adolescents.     

Using the Strengths and Difficulties Questionnaire (SDQ) to screen for child psychiatric disorders in a community sample

Child psychiatric disorders are common and treatable, but often go undetected and therefore remain untreated. To assess the Strengths and Difficulties Questionnaire (SDQ) as a potential means for improving the detection of child psychiatric disorders in the community, SDQ predictions and independent psychiatric diagnoses were compared in a community sample of 7984 5-15 year olds from the 1999 British Child Mental Health Survey. Multi-informant (parents, teachers, older children) SDQs identified individuals with a psychiatric diagnosis with a specificity of 94.6% (95% Cl, 94.1-95.1%) and a sensitivity of 63.3% (59.7-66.9%). The questionnaires identified over 70% of individuals with conduct, hyperactivity, depressive, and some anxiety disorders, but fewer than 50% of individuals with specific phobias, separation anxiety and eating disorders. Sensitivity was substantially poorer with single-informant rather than multi-informant SDQs. Community screening programmes based on multi-informant SDQs could potentially increase the detection of child psychiatric disorders, thereby improving access to effective treatments.

Manualized supportive-expressive psychotherapy versus nonmanualized community-delivered psychodynamic therapy for patients with personality disorders: bridging efficacy and effectiveness

OBJECTIVE: Time-limited manualized dynamic psychotherapy was compared with community-delivered psychodynamic therapy for outpatients with personality disorders. METHOD: In a stratified randomized clinical trial, 156 patients with any personality disorder diagnosis were randomly assigned either to 40 sessions of supportive-expressive psychotherapy (N=80) or to community-delivered psychodynamic therapy (N=76). Assessments were made at intake and 1 and 2 years after intake. Patients were recruited consecutively from two community mental health centers (CMHCs), assessed with the Structural Clinical Interview for DSM-IV Axis II Personality Disorders, and included if they had a diagnosis of any DSM-IV personality disorder. The outcome measures included the presence of a personality disorder diagnosis, personality disorder severity index, level of psychiatric symptoms (SCL-90), Global Assessment of Functioning Scale score, and number of therapy sessions. General mixed-model analysis of variance was used to assess group and time effects. RESULTS: In both treatment conditions, the global level of functioning improved while there were decreases in the prevalence of patients fulfilling criteria for a personality disorder diagnosis, personality disorder severity, and psychiatric symptoms. There was no difference in effect between treatments. During the follow-up period, patients who received supportive-expressive psychotherapy made significantly fewer visits to the CMHCs than the patients who received community-delivered psychodynamic therapy. CONCLUSIONS: Manualized supportive-expressive psychotherapy was as effective as nonmanualized community-delivered psychodynamic therapy conducted by experienced dynamic clinicians.     

Child and adolescent psychopathology in a developing country: testing the validity of the strengths and difficulties questionnaire (Urdu version)

A study to test the validity of the Urdu version of the Strengths and Difficulties Questionnaire (SDQ) was carried out in Pakistan. The study population consisted of 212 children aged 4 to 16 years presenting to psychiatric (case group: n = 72) and paediatric outpatient clinics (comparison group: n = 140). Parents of these children were interviewed using the extended version of the SDQ. The case group was further subjected to diagnostic ICD-10 criteria by child psychiatrists, who were blind to SDQ scores. The Urdu version was able to discriminate between the study groups. The mean difficulties score was higher in the case group (mean = 21.7) than the comparison group (mean = 14.4), the difference (mean difference = 7.3) being statistically significant (p < 0.01, 95% CI = 5.3, 9.3) with an effect size of 1.1. Adequate sensitivity (> or = 61%) was obtained for each type of psychiatric disorder in the case group using the abnormal category of the SDQ symptom scores as a cutoff. A simple 'pencil-and-paper' algorithm combining symptom and impact scores further identified children in need of intervention. A ROC curve analysis showed an area under the curve > 0.70 for all scores. The choice of optimal cutoffs for the Urdu version is discussed.     

Bipolar II disorder and comorbidity

The validity and reliability of the diagnosis of bipolar II disorder has been questioned by means of comorbidity with nonaffective disorders, including substance abuse, personality disorders, and anxiety disorders. This study examined the comorbid diagnosis of a sample of bipolar II patients, comparing patients with comorbidity and those with "pure" bipolar II disorder. Forty Research Diagnostic Criteria (RDC) bipolar II patients were assessed by means of the Schedule for Affective Disorders and Schizophrenia, Lifetime Version (SADS-L) and Structured Clinical Interview for DSM-III-R axis I (SCID-II) for personality disorders. Patients fulfilling RDC criteria for any psychiatric disorder (except personality disorders) or DSM-IV criteria for any personality disorder were compared with patients without comorbidity. For practical reasons, cyclothymia was not considered as a comorbid diagnosis. Half of the sample had lifetime comorbidity with other psychiatric disorders, mainly personality disorders (33%), substance abuse or dependence (21%), and anxiety disorders (8%). However, only the rates of suicidal ideation (74% v 24%, chi square [chi2] = 9.03, P = .003) and suicide attempts (45% v 5%, chi2 = 8.53, P = .003) were significantly different between patients with and without comorbidity. In summary, although the rates of comorbidity are relatively high in bipolar II disorder, most clinical and course variables are strikingly similar in patients with and without comorbidity except for suicidal behavior, suggesting that comorbidity does not reduce the validity of the diagnosis of bipolar II disorder.
