Prevalence of chronic benign pain disorder among adults: A review of the literature.

Abstract In this review epidemiological studies concerning chronic benign pain among adults are discussed. To this end, studies focusing on chronic pain, reporting prevalences at a population or primary health care level, including subjects aged between 18 and 75 years have been collected and analyzed. Focus of analysis was on research methods, definitions of chronic benign pain used, and reported prevalences. Prevalences varied between 2% and 40% of the population. Nor method used (telephone survey, postal survey, nor definition of chronicity (>1 month; >3 months; >6 months) clearly explained the differences in prevalence in the various studies. Implications for future research are discussed.

The Netherlands Study of Depression and Anxiety (NESDA): rationale, objectives and methods.

The Netherlands Study of Depression and Anxiety (NESDA) is a multi‐site naturalistic cohort study to: (1) describe the long‐term course and consequences of depressive and anxiety disorders, and (2) to integrate biological and psychosocial research paradigms within an epidemiological approach in order to examine (interaction between) predictors of the long‐term course and consequences.

Help seeking for emotional and behavioural problems in children and adolescents: a review of recent literature.

Abstract.In order to understand the discrepancy between rates of child and adolescent psychopathology and rates of mental health service use, variables influencing the help-seeking process need to be investigated. The present article aims to extend and refine previous findings by reviewing 47 recent empirical studies on parental and adolescent problem recognition and help seeking, and problem recognition by the general practitioner (GP). Several variables (child age, the presence of medical and school-related problems, informal help seeking, past treatment of parents or relatives, family size, and type of maltreatment) were discovered to influence parental/adolescent problem recognition and/or help seeking,while refinements were found for the effects of type of psychopathology, child gender, adolescent attitudes and personality, parental psychopathology, social support, and sociodemographic variables. Although recent studies uncovered several determinants of problem recognition by the GP (child gender, age, past treatment, academic problems, family composition, life events, type of visit, and acquaintance with child), this aspect of the help-seeking pathway remains relatively uncharted and, therefore, needs to be the focus of future research.

Two-year course of depressive and anxiety disorders: Results from the Netherlands Study of Depression and Anxiety (NESDA).

BACKGROUND Whether course trajectories of depressive and anxiety disorders are different, remains an important question for clinical practice and informs future psychiatric nosology. This longitudinal study compares depressive and anxiety disorders in terms of diagnostic and symptom course trajectories, and examines clinical prognostic factors. METHODS Data are from 1209 depressive and/or anxiety patients residing in primary and specialized care settings, participating in the Netherlands Study of Depression and Anxiety. Diagnostic and Life Chart Interviews provided 2-year course information. RESULTS Course was more favorable for pure depression (n=267, median episode duration = 6 months, 24.5% chronic) than for pure anxiety (n=487, median duration = 16 months, 41.9% chronic). Worst course was observed in the comorbid depression-anxiety group (n=455, median duration > 24 months, 56.8% chronic). Independent predictors of poor diagnostic and symptom trajectory outcomes were severity and duration of index episode, comorbid depression-anxiety, earlier onset age and older age. With only these factors a reasonable discriminative ability (C-statistic 0.72-0.77) was reached in predicting 2-year prognosis. LIMITATION Depression and anxiety cases concern prevalent - not incident - cases. This, however, reflects the actual patient population in primary and specialized care settings. CONCLUSIONS Their differential course trajectory justifies separate consideration of pure depression, pure anxiety and comorbid anxiety-depression in clinical practice and psychiatric nosology.

Factors associated with adolescent mental health service need and utilization.

OBJECTIVE To determine the association of parent, family, and adolescent variables with adolescent mental health service need and utilization. METHOD Correlates of adolescent mental health service utilization, self-perceived need and unmet need were investigated in a general population sample of 1,120 Dutch adolescents aged 11 to 18 years (78% response rate). RESULTS 3.1% of the sample had been referred for mental health services within the preceding year, and 3.8% reported unmet need. 7.7% of adolescents at risk for psychopathology, and 17.8% of those indicating a need for help, had been referred. Family stress and adolescents self-reported problems were most strongly associated with service need and utilization. Internalizing problems, female gender, and low education level were associated with self-perceived unmet need. Adolescent ethnicity and competence in activities and school were associated with service use, but did not influence service need, while the opposite effect was found for adolescent age and parental psychopathology. CONCLUSION In designing intervention programs aimed at increasing adolescent mental health service use, distinctions should be made between efforts focused at adolescents not recognizing their problems, and those with unmet need.

Electronic diary assessment of pain, disability and psychological adaptation in patients differing in duration of pain

Abstract Computerized diary measurement of pain, disability and psychological adaptation was performed four times a day for 4 weeks in 80 patients with various duration of unexplained pain. Reported are (1) the temporal characteristics and stability of pain report during the 4‐week measurement period, (2) the association between pain duration and pain report, disability and general psychopathology, and (3) the accordance between diary assessment versus questionnaire assessment of pain, disability and psychological adaptation. No evidence of instrument reactivity was found: pain report was stable across the 4‐week period. However, pain report appeared to be highly variable both between and within days. About half the patients showed a clear increasing trend in pain during the day. Several differences were found between subgroups of patients varying in pain duration. Patients with less than 6 months of pain reported significantly less pain intensity, disability and fatigue than patients whose pain persisted for more than 6 months. Pain coping and responses to pain behaviors by the spouse also differed for the subgroups: longer pain duration was associated with increased catastrophizing and solicitous responses from the spouse. Comparison of scores obtained with diary versus questionnaire assessment indicated moderate correlations for most variables. Retrospective (questionnaire) assessment of pain intensity yielded significantly higher pain scores than diary assessment.

Measuring mental health of the Dutch population: a comparison of the GHQ-12 and the MHI-5

BackgroudThe objective is to compare the performance of the MHI-5 and GHQ-12, both measures of general mental health. Therefore, we studied the relationship of the GHQ-12 and MHI-5 with sociodemographic characteristics, self-reported visits to general practice and mental health care, and with diagnoses made by the general practitioner.MethodsData were used from the Second Dutch National Survey of General Practice, which was carried out in 104 practices. This study combines data from a representative sample of the Dutch population with data from general practice.ResultsThe agreement between the GHQ-12 and MHI-5 is only moderate. Both instruments are however similarly associated with demographic characteristics (except age), self-reported health care use, and psychological and social diagnoses in general practice.ConclusionsThe performance of the MHI-5 and GHQ-12 in terms of predicting mental health problems and related help seeking behaviour is similar. An advantage of the MHI-5 is that it has been widely used, not only in surveys of mental health, but also in surveys of general health and quality of life, and it is shorter. A disadvantage of the MHI-5 is that there is no cut-off point. We recommend a study to establish a valid, internationally comparable cut-off point.

Communication: the royal pathway to patient-centered medicine.

The papers in this special issue on communication in health care can be summarized in one easy and powerful message: communication is the royal pathway to patient-centerd medicine. Approached from differen angles, the linkage between communication and patient-centered medicine is the common theme that is covered by all authors. Underlying are two distinct assumptions: the first is, that patient-centerd medicine is a relevant aim in health care; the second, that communication is an important tool to achieve that aim. Both assumptions deserve some explorations. (aut. ref.)

Detecting depressive and anxiety disorders in distressed patients in primary care; comparative diagnostic accuracy of the Four-Dimensional Symptom Questionnaire (4DSQ) and the Hospital Anxiety and Depression Scale (HADS)

BackgroundDepressive and anxiety disorders often go unrecognized in distressed primary care patients, despite the overtly psychosocial nature of their demand for help. This is especially problematic in more severe disorders needing specific treatment (e.g. antidepressant pharmacotherapy or specialized cognitive behavioural therapy). The use of a screening tool to detect (more severe) depressive and anxiety disorders may be useful not to overlook such disorders. We examined the accuracy with which the Four-Dimensional Symptom Questionnaire (4DSQ) and the Hospital Anxiety and Depression Scale (HADS) are able to detect (more severe) depressive and anxiety disorders in distressed patients, and which cut-off points should be used.MethodsSeventy general practitioners (GPs) included 295 patients on sick leave due to psychological problems. They excluded patients with recognized depressive or anxiety disorders. Patients completed the 4DSQ and HADS. Standardized diagnoses of DSM-IV defined depressive and anxiety disorders were established with the Composite International Diagnostic Interview (CIDI). Receiver Operating Characteristic (ROC) analyses were performed to obtain sensitivity and specificity values for a range of scores, and area under the curve (AUC) values as a measure of diagnostic accuracy.ResultsWith respect to the detection of any depressive or anxiety disorder (180 patients, 61%), the 4DSQ and HADS scales yielded comparable results with AUC values between 0.745 and 0.815. Also with respect to the detection of moderate or severe depressive disorder, the 4DSQ and HADS depression scales performed comparably (AUC 0.780 and 0.739, p 0.165). With respect to the detection of panic disorder, agoraphobia and social phobia, the 4DSQ anxiety scale performed significantly better than the HADS anxiety scale (AUC 0.852 versus 0.757, p 0.001). The recommended cut-off points of both HADS scales appeared to be too low while those of the 4DSQ anxiety scale appeared to be too high.ConclusionIn general practice patients on sick leave because of psychological problems, the 4DSQ and the HADS are equally able to detect depressive and anxiety disorders. However, for the detection of cases severe enough to warrant specific treatment, the 4DSQ may have some advantages over the HADS, specifically for the detection of panic disorder, agoraphobia and social phobia.

Detection of psychologic complaints by general practitioners.

Many complaints, which present as somatic illness at a medical visit, appear afterwards to be partly psychologic in origin. Not every general practitioner (GP), however, is equally sensitive to the psychologic aspects, and not every physician possesses the communication techniques required to detect them. In this respect, it has been considered important that a GP show attention, interest and concern; have a patient-centered attitude; clarify complaints; structure the interview; and have an active, seeking attitude. In this research project the effects of these factors on a patients presentation of personal problems were investigated; the relationship between the GPs way of communicating and his or her sensitivity to the psychologic aspects of complaints was examined. It appeared that the features of physician-patient interaction, mentioned above are complementary; it was possible to identify one conversational style, expressed by a factorscore, based on measurements of the several distinct features. This conversational style appeared to be a good predictor of a physicians initiatives in asking for a patients problems, but a negative predictor of a patients initiatives in presenting them. Hence, when a physician communicated in an open, patient-centered way, the patient did not need to take those initiatives; if the patient did so, it was in most cases a sign of the physicians unresponsive attitude. The open conversational style of the physician was related to his sensitivity to the psychologic aspects of complaints. The consequences of these findings for vocational and postgraduate training are discussed
