Abstract
OBJECTIVE Post-stroke depression is a frequent complication of stroke that has detrimental consequences for quality of life and functional outcomes. Daily life routines may increase feelings of security for some individuals confronted with age-related health concerns, but little information is available concerning their role following stroke. The aim of this investigation was to examine the association of depression and other psychological variables at hospitalization for stroke and behavioral routines and mood symptoms three months later using Ecological Momentary Assessment (EMA). METHODS Forty-four patients with minor ischemic stroke were consecutively enrolled in the study. Stroke severity, handicap, depression and anxiety symptoms were assessed at baseline. EMA data acquired three months later were coded for the repetition of specific activities or behaviors occurring within the same time period across days. RESULTS Higher baseline depression and anxiety symptom severity were significantly associated with increased behavioral routines three months after stroke. The occurrence of routines was associated with a higher level of depressive symptomatology over subsequent hours of the day. CONCLUSION The findings demonstrate a general correlation between baseline psychological vulnerability and routines three months later, but within-day analyses suggest that routines may increase the risk of negative affect in this vulnerable population.

Abstract
AbstractThis naturalistic, prospective investigation examined the role of fear of negative evaluation and the personality trait of harm avoidance in the anxiety levels of treated social phobia patients. One hundred and fifty-seven patients with DSM-IV social phobia were assessed before starting treatment and were then followed for up to two years. As expected, greater fear of negative evaluation and higher scores of harm avoidance were associated with greater anxiety at the 6 month follow-up, and harm avoidance remained a significant predictor at 24 months. However, no evidence was found for an interaction between the personality and cognitive variables examined. The findings are discussed in terms of the relative independence of these factors, as well as their potential implications for the treatment of this disorder.

Abstract
IntroductionExperiences of depression and anxiety are common among patients with persecutory delusions. It has been theorized that emotional disturbances affect the formation and appraisal of persecutory delusions directly and possibly via increasing the sense of aberrant salience.ObjectivesUsing a time-lagged analysis of experience sampling data, this study modelled the role of momentary levels of negative emotions and aberrant salience in maintaining persecutory delusions in patients with active delusions.MethodsClinically acute participants with at least a mild level of persecutory delusions were assessed using experience sampling method (ESM; 7 entries per day for 14 days) and clinical rating scales. ESM data of participants who completed at least 30 ESM entries were analysed by using multilevel regression modelling.ResultsThe final sample consisted of 14 participants, with a total of 1161 momentary observations. Time-lagged analysis revealed that both negative emotions (B = 0.125, P = .009) and aberrant salience (B = 0.267, P< .001) predicted an increase in persecutory delusions in the next moment. Conversely, persecutory delusions did not predict change in negative emotions or change in aberrant salience in the next moment (ps> .05). Negative emotions also predicted an increase in aberrant salience in the next moment (B = 0.087, P = .009).ConclusionsOur results supported the hypothesis that both negative emotions and aberrant salience exacerbate persecutory delusions, rather than being merely the sequelae of the symptoms. Our results suggested both direct and indirect (via aberrant salience) pathways from negative emotions to persecutory delusions.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Abstract
Objective
There is a need to identify determinants of neurocognitive impairment among older persons living with HIV (PLHIV). Utilizing smartphone-based Ecological Momentary Assessment (EMA) and mobile cognitive testing, we examined the relationships between daily life activities and real-world neurocognitive performance among older PLHIV and HIV-uninfected adults.
Method
Ninety-one participants (58 PLHIV; Mage = 59.4, SD = 6.4), 70.3% male, 65.9% non-Hispanic white, completed four smartphone-based EMA surveys of daily activities and one mobile color-word interference test (mCWIT) per day for 14 days. Daily activities were grouped into five categories: activities of daily living (ADLs, IADLs), cognitively demanding activities, socially-engaging activities, physical activity (PA), and passive leisure activity (watching TV). Data was collapsed across the 14 days to examine between-person effects of the proportion of time reportedly spent on each activity on neurocognitive outcomes (the average correct responses and completion time for the mCWIT).
Results
No effect was found for engaging in activities by HIV status; however, PLHIV had significantly longer times on the mCWIT compared to persons without HIV (t = 2.49; 95% CI: 0.60, 5.37; p = 0.02). In a multivariable regression model accounting for HIV status, a greater proportion of time spent watching TV was associated with slower average mCWIT performance (beta = 9.41; 95% CI: 1.88,17.0; p = 0.01). There were no relationships between other domains of daily life activities and mCWIT performance.
Conclusion
Our findings provide evidence that more time spent watching TV is associated with slower mCWIT performance. Future work examining the time-lagged relationships between these variables is needed to understand whether watching TV decreases real-time neurocognitive performance.

Abstract
BackgroundSuicidal behaviors result from a complex interaction between social stressors and individual vulnerability. Ecological Momentary Assessment (EMA) provides the opportunity to investigate the relationship between social stressors in daily life and the occurrence of negative thoughts leading to suicidal ideation. fMRI showed that a neural network supports the sensitivity to social stressors in suicide attempters.ObjectiveA joint fMRI/EMA study investigated whether individual differences in brain reactivity to scanner-based social rejection was related to social rejection during real-world social interactions.MethodSixty women were included: euthymic women with a history of depression with or without suicidal behavior and healthy controls. The Cyberball Game was used as a social exclusion paradigm. Following the fMRI, subjects used EMA for seven days, providing data on environmental, contextual and emotional factors.ResultsIn the fMRI study, in comparison to patients without any history of suicide attempt and healthy controls, suicide attempters showed decreased activation in the posterior cingulate cortex, insula and superior temporal gyrus during the exclusion vs. inclusion condition. In the EMA study, social stressors were specific predictors of suicidal ideation in suicide attempters. We will examine here if individuals who show greater activity in specific brain regions during scanner-based social rejection reported a greater social distress during their daily social interactions.Conclusionsthis study used a combined technique to assess whether neural reactivity to experimental social rejection in the scanner is related to real-world social experience, and if it may help to understand the sensitivity to social stress in suicidal behavior.Disclosure of interestThe authors declare that they have no competing interest.

Abstract
Investigations of migraine comorbidity have confirmed its association with diverse psychiatric conditions. This association appears to be strongest for major depression and anxiety disorders (particularly panic and phobia), but increased comorbidity has also been reported with substance abuse and certain mood disorders. This literature also indicates that greater psychiatric comorbidity exists for migraine sufferers with aura than without. Some support is found for the notion that psychiatric comorbidity is higher in transformed migraine than in simple migraine (particularly in the case of chronic substance abuse). However, research into the possible mechanisms underlying these associations remains limited. Studies examining the order of onset and the cross-transmission of migraine and psychiatric disorders in families have been unable to distinguish fully between causal and common aetiological models of association. The conclusions are discussed in light of both methodological and conceptual issues relevant to understanding migraine comorbidity.

Abstract
OBJECTIVE The state-of-the-art tools of neurology, in particular modern neuroimaging techniques, have yet to benefit from the revolution in mobile technologies that provide new insights into the mechanisms underlying clinical syndromes. This study demonstrates the manner in which mobile technologies may provide information that is complementary to MRI data, using the illustration of poststroke depression. METHODS MRI examinations were provided to 15 stroke patients, followed by computerized ambulatory monitoring of daily life experiences over 1 week. RESULTS The occurrence of daily life events was significantly associated with the intensity of positive affect during the ambulatory monitoring period. This emotional reactivity was also significantly associated with functional connectivity in brain regions linked with the risk of depression 3 months following stroke. CONCLUSIONS Novel mobile technologies provide information that is inaccessible to hospital-based tests, and allow for more complete investigations of disorder expression and etiology.

Abstract
BACKGROUND Computerized ambulatory monitoring provides real-time assessments of clinical outcomes in natural contexts, and it has been increasingly applied in recent years to investigate symptom expression in a wide range of disorders. The purpose of this study was to examine the feasibility and validity of this data collection strategy with adult stroke patients. METHODS Forty-eight individuals (75% of the contacted sample) agreed to participate in the current study and were instructed to complete electronic interviews using a personal digital assistant 5 times per day over a 1-week period. RESULTS More than 80% of programmed assessments were completed by the sample, and no evidence was found for fatigue effects. Expected patterns of associations were observed among daily life variables, and data collected through ambulatory monitoring were significantly correlated with standard clinic-based measures of similar constructs. CONCLUSION Support was found for the feasibility and validity of computerized ambulatory monitoring with stroke patients. The application of these novel methods with stroke patients should provide complementary information that is inaccessible to standard hospital-based assessments and permit increased understanding of the significance of clinical results and test scores for daily life experience.

Abstract
BACKGROUND Although mental disorders have been shown to predict subsequent substance disorders, it is not known whether substance disorders could be cost-effectively prevented by large-scale interventions aimed at prior mental disorders. Although experimental intervention is the only way to resolve this uncertainty, a logically prior question is whether the associations of mental disorders with subsequent substance disorders are strong enough to justify mounting such an intervention. We investigated this question in this study using simulations to estimate the number of substance disorders that might be prevented under several hypothetical intervention scenarios focused on mental disorders. METHOD Data came from the National Comorbidity Survey Replication (NCS-R), a nationally representative US household survey that retrospectively assessed lifetime history and age of onset of DSM-IV mental and substance disorders. Survival analysis using retrospective age-of-onset reports was used to estimate associations of mental disorders with subsequent substance dependence. Simulations based on the models estimated effect sizes in several hypothetical intervention scenarios. RESULTS Although successful intervention aimed at mental disorders might prevent some proportion of substance dependence, the number of cases of mental disorder that would have to be treated to prevent a single case of substance dependence is estimated to be so high that this would not be a cost-effective way to prevent substance dependence (in the range 76-177 for anxiety-mood disorders and 40-47 for externalizing disorders). CONCLUSIONS Treatment of prior mental disorders would not be a cost-effective way to prevent substance dependence. However, prevention of substance dependence might be considered an important secondary outcome of interventions for early-onset mental disorders.

Abstract
BACKGROUND Euthymic states in bipolar disorders are usually considered to be lacking serious psychiatric disorders. Moreover, recent results prove the need to take an interest in a potential emotional dysregulation during these intercrisis periods. Therefore, it seems relevant not only to focus on the emotions tonality (sadness/euphoria) felt by patients, but also on the intensity of their emotional background. Several reasons argue for a disturbance of emotional reactivity in euthymic bipolar patients. First, most bipolar patients spontaneously claim they have a higher sensitivity than average, which may lead to extreme emotional reactions, even during intercrisis periods. Secondly, the emotional reactivity is a way to raise the question of the bipolar patients' vulnerability to stress in euthymic periods. Several studies have shown the impact of stressful life events on the rate of relapse into bipolar disorders. The aim of this study is to examine the emotional reactivity of euthymic bipolar patients in comparison with a control group, using a test of emotional induction. Our hypothesis is that euthymic bipolar patients have a higher emotional reactivity than controls. METHOD One hundred and forty-five subjects were recruited: 90 controls and 55 euthymic bipolar patients. The patients were interviewed by a trained psychologist using the French version of the DIGS providing DSM-IV diagnosis. The euthymic state was confirmed with both MADRS (score<12) and Bech's Manic Scale (score<4). The subjective emotional reactivity of the subjects was assessed using a method of emotional induction, based on viewing a set of 18 (positive, negative or neutral) pictures. The subjects have to appreciate the valence (pleasant, neutral or unpleasant thoughts) and assess the arousal (degree of emotion triggered by each picture). RESULTS On average, euthymic bipolar patients report the same valence and arousal to positive (F [1.143]=0.18, p=0.68) and negative (F [1.143]=0.52, p=0.47) pictures as control subjects. Neutral pictures, however, were considered more pleasant and moving by euthymic bipolar patients than by control subjects (F [1.143]=8.40, p=0.004). CONCLUSION Euthymic bipolar patients seem to present an emotional hyperactivity which occurs especially in neutral situations. These results partly corroborate outcomes of other authors, while providing a new methodology through the emotional induction test. The highlight of emotional hyperreactivity during intercrisis periods allows us to understand differently the topic of specific vulnerability to stress of bipolar patients. This hypersensitivity could lead to thymic decompensations and could be linked with an emotional dysregulation, potential endophenotype of the bipolar pathology. Beyond the interest in understanding the physiopathology of the bipolar disorder, it could be associated with several clinical applications as well as in the psychoeducational field and in the screening of the individual risk within the family of bipolar subjects.

Abstract
BACKGROUND Hispanics in the USA have higher rates of substance use disorders than similar ethnic groups residing in Latin American nations, and recent evidence suggests an increase in substance use among US Hispanic youth. This investigation examines the familial and societal correlates of this increase by comparing Puerto Rican families residing in the mainland USA and Puerto Rico. METHODS Using migrant and controlled family study methods, 279 probands in San Juan and 236 probands in New Haven were recruited from treatment clinics and the general community to compose four diagnostic groups: drug abuse/dependence; alcohol abuse/dependence; psychiatric controls; unaffected controls. 806 biological offspring aged 12-17 were then directly interviewed. RESULTS Total rates for alcohol use were greater among San Juan youth than their migrant counterparts. By contrast, US migrant adolescents were more likely to use cannabis. A strong association was observed between parental and child substance use at both sites, particularly for boys, and offspring of probands with drug use disorders were at greatest risk for substance use and related disorders. Familial aggregation patterns did not vary substantially by site. CONCLUSIONS Despite societal influences on the magnitude and patterns of substance use in migrant youth, the consistent influence of parental disorders across sites reveals that the cross-generational transmission of substance use disorders in prior studies extends to Hispanic families and is an important factor to consider in the development of prevention strategies.

Abstract
BACKGROUND The 'gateway' pattern of drug initiation describes a normative sequence, beginning with alcohol and tobacco use, followed by cannabis, then other illicit drugs. Previous work has suggested that 'violations' of this sequence may be predictors of later problems but other determinants were not considered. We have examined the role of pre-existing mental disorders and sociodemographics in explaining the predictive effects of violations using data from the US National Comorbidity Survey Replication (NCS-R). METHOD The NCS-R is a nationally representative face-to-face household survey of 9282 English-speaking respondents aged 18 years and older that used the World Health Organization (WHO) Composite International Diagnostic Interview (CIDI) to assess DSM-IV mental and substance disorders. Drug initiation was estimated using retrospective age-of-onset reports and 'violations' defined as inconsistent with the normative initiation order. Predictors of violations were examined using multivariable logistic regressions. Discrete-time survival analysis was used to see whether violations predicted progression to dependence. RESULTS Gateway violations were largely unrelated to later dependence risk, with the exception of small increases in risk of alcohol and other illicit drug dependence for those who initiated use of other illicit drugs before cannabis. Early-onset internalizing disorders were predictors of gateway violations, and both internalizing and externalizing disorders increased the risks of dependence among users of all drugs. CONCLUSIONS Drug use initiation follows a strong normative pattern, deviations from which are not strongly predictive of later problems. By contrast, adolescents who have already developed mental health problems are at risk for deviations from the normative sequence of drug initiation and for the development of dependence.

Abstract
BACKGROUND The post-partum blues is a transient mood alteration affecting most women a few days after delivery. Its stereotypic pattern of symptoms and time course, peaking on post-partum day 3-5, is suggestive of biological determinants superimposed on psycho-social factors. This study was designed to evaluate the possible role of the serotonin system during this period through assessment of brain tryptophan availability. METHODS Blood samples from 50 women were collected just before (D0) and 3 days after (D3) delivery. Based on plasma concentration of tryptophan, amino acids competing with tryptophan for transport across the blood-brain barrier and on their respective affinities for this transporter, a brain tryptophan availability index (BTAI) was calculated and its variation correlated with the intensity of post-partum blues evaluated through the Kennerley and Gath score at D3. RESULTS The BTAI showed a -15% decrease between D0 and D3 (p < 0.01, paired t-test). This decrease was not supported by a drop in plasma tryptophan since its level rather increased (+19%). There was no evidence for change in placental indoleamine-2,3-dioxygenase activity since the variation in plasma l-kynurenine (+12%) paralleled the change in tryptophan level. The decreased BTAI appeared the consequence of a dramatic increase in plasma levels of most amino acids, particularly the competitor aminoacids leucine, isoleucine, valine and tyrosine, during the early post-partum. This decrease in brain tryptophan availability was concomitant to the post-partum blues, whose intensity significantly correlated with the amplitude of BTAI variation (Pearson's coefficient -0.283, p < 0.05). CONCLUSION This study suggests that generalized, large amplitude metabolic and/or nutritional changes occurring in the early post-partum result in a transient decrease in brain tryptophan availability, partly accounting for the mood alteration referred to as the post-partum blues, a model for the triggering of puerperal mood disorder in vulnerable women.

Abstract
BACKGROUND Within days following birth, most women are showing signs of mood changes, commonly named baby blues. Due to the frequency of this condition, baby blues is considered as a physiological state probably associated to biological modifications. Some studies have shown an existing link between the intensity of the baby blues and post-partum mood disorder. Therefore, it seems important to report and explore in more details the clinical background related the condition. The aim of this study was to demonstrate the possibility of a link between the intensity of the baby blues and some specific factors like maternal self-esteem, maternal childcare stress and social background, and also to define the symptoms of the baby blues from core dimensions in mood disorders. METHOD Mothers were recruited few hours before giving birth in a teaching hospital. At the third day following birth, an appointment was made to obtain the necessary information (past medical history and social history) and history of previous mood disorders. The mood was evaluated from the scale of the intensity of baby blues from Kennerly and Gath (1989). Moreover, evaluations at day 3 and week 6 post birth of self-esteem in relation to motherhood (Maternal self-report Inventory from Shea and Tronick, 1988), stress in relation with the care of the baby (Childcare Stress Inventory from Cutrona, 1983) and the social support (Social Support scale from Bruchon-Schweitzer, 1998) were undertaken. RESULTS 95 women were included in the final sample. The intensity of the baby blues was explained by the type of pregnancy (p=0.002), a low maternal self-esteem (p=0.025), high levels of stress in relation to the care of the baby (p=0.074). The basic clinical characteristic of the baby blues seems to be due to an increase in the emotional reaction with a sharp feelings, leading to a lability rather than an affect sad tonality. CONCLUSION The baby blues seems to be a physiological process whereby the intensity is influenced by psychological factors. Consequently the diminution of self-esteem with motherhood and the increase of stress in relation to the care of the baby appeared to be significant factors in the intensity of the baby blues. Moreover, the clinical characteristics found in this study implies that the baby blues is more related to hypomania rather than to depression syndrome. This non-pathological state could be the first stage leading to a puerperal psychosis in predisposed women, which is mainly characterized by manic symptoms.

Abstract
UNLABELLED The International Consortium of Psychiatric Epidemiology has confirmed the high comorbidity in community-drawn samples between substance use disorders and anxiety or depression. In the same way, associations between substance use and specific personality traits (such as novelty seeking, harm avoidance or antisocial personality) have also been extensively documented. Self-medication and social deviance are among the most commonly evoked explanatory models for these forms of comorbidity, and are based on findings that affective disorders and specific personality traits often precede the onset of substance use disorders. The self-medication model postulates that an individual chooses a specific substance according to its psychopharmacologic action on the given psychological state of the person. By contrast, the social deviance model posits that this form of comorbidity is due to the fact that persons consuming certain substances may have affective or personality characteristics that are more severe or more deviant than non-consumers (or than consumers of socially well-accepted substances). In this way, the individual does not use a particular substance to assuage pre-existing disorders but, due to a more deviant personality, is less influenced by social norms and may more easily turn to using illicit substances or to polyconsumption. However, a major limitation of the current scientific literature concerning tests of these models is that previous investigations have been based in overwhelming majority on clinical populations. The examination only of clinical samples renders difficult the identification of causal (or primary) risk factors for the emergence of substance use disorders from the potential consequences of substance use itself. The goal of the current study was therefore to simultaneously compare both models of association using a non clinical population of substance users. In addition to selecting subjects based on use (rather than abuse or dependence), multiple comparisons were corrected with a Bonferroni adjustment. METHOD A two-phase sampling plan was used with post-stratification on substances use. In the first stage, an initial sample of 685 students was pre-selected based on responses to a battery of self-questionnaires, including information concerning recent consumption of substances (alcohol, cannabis, cocaine, heroin, acid, solvents, and so on), anxiety levels measured by the State and Trait Anxiety Inventory (STAI, Spielberger, 1983) and depression levels evaluated by the Center of Epidemiologic Studies Depression Scale (CES-D, Radloff, 1977). Based on responses to these questionnaires, 98 subjects were selected in the second phase to compose four groups of substance users: non consumers (those who did not use any substance during the last month); consumers of alcohol only, consumers of cannabis (with or without alcohol) and consumers of other illicit substances (with or without cannabis or alcohol). These subjects were then invited to participate in a brief laboratory-based meeting where they completed the Temperament and Character Inventory (TCI, Cloninger, 1992), which assessed different personality characteristics such as novelty seeking (NS), harm avoidance (HA) or antisocial personality disorder (APD). ANALYSES The hypotheses concerning self-medication were tested by multiple logistic regression by comparing each group of substance consumption to the non-consumer group relative to levels of anxiety, depression and scores of novelty seeking and harm avoidance. The social deviance model was tested by ANOVAs using contrasts which allowed for a test of a linear tendency across the four groups of consumption relative to each of the personality traits (novelty seeking, harm avoidance and antisocial personality). RESULTS Results of multiple logistic regressions showed no difference between non-consumers and any group of consumers with regard to anxiety, depression and harm avoidance. However, consumers of other illicit substances significantly differed from non-consumers for novelty seeking trait (qOR=8.4; p<0.05). Results of the ANOVA also showed no differences between the four groups with regard to scores of harm avoidance and level of antisocial personality but again a comparison of novelty seeking scores was significant, F(94)=6.46, p<0.05. Moreover, the contrast method demonstrated that novelty seeking scores increased linearly and significantly (p<0.001) from the group of non-consumers to the group of the consumers of the most deviant substances. CONCLUSION The results obtained in this non-clinical sample are in favor of social deviance model which posits that the personality trait of novelty seeking is associated to the consumption of the most illicit and deviant substances (such as heroin or cocaine). On the other hand, no support was found for the hypothesis of self-medication which assumes that specific substances should be particularly associated with specific psychological characteristics or vulnerabilities.

Abstract
Headache patients frequently overuse analgesic medications: 20% of the patients from headache centers is concerned by this problem, which has been estimated to occur in four percent of the community migrainers. Frequent use of various types of headache medication may paradoxically cause an increase in headache attack frequency as well as their chronicisation due to potentially complex mechanisms of sensitization. Patients will enter into a self- perpetuating cycle of daily headaches and use of symptomatic medications which can lead to addiction and to social and occupational impairement. Indeed, many patients will experience pharmacological tolerance and dependence but also by some kind of craving. International Headache Society qualify these patients as abusers referring mostly to the amount of substance ingested. Hence patients are labelled analgesic abusers . However, as many of these analgesic medications contained psychotropic substances (i.e. caffeine, codeine.), these patients may fulfill DSM IV criteria of dependance. Nevertheless, the dependance criteria should be adapted to chronic pain patients. Indeed, if pharmacological dependence and tolerance criteria are easy to apply in such patients, it is not the case for the criteria a great deal of time spent to obtain substances, to use substances or to recover from substances effects . As analgesic medications are legally obtained from medical practitioners, drug seeking behaviours are mostly: obtaining medications from multiple providers, repeating episodes of prescription loss and multiplying requests for early refills. Moreover the detrimental effects of analgesic abuse on psychosocial functioning is likely to be related to pain rather than to medication overuse. Finally the best indicator of addictive behaviors in such patients, is the loss of control over the use of analgesic medication despite the adverse consequences over pain. Comorbidity with addiction to other substances has never been specifically scrutinized in this population, but it is well documented that chronic pain patients have high rates of addiction with various types of substances. Moreover, it is well documented that these patients are at higher risk for anxious (panic disorders and phobic disorders) and depressive disorders than non abusing headache patients. Anxiety and depressive scores are related to both the chronicity of headaches, and the amount of analgesic intake. Therefore, this comorbidity is possibly related to psychoactive substance use but there is no prospective study concerning chronological link between the anxious and depressive disorders and analgesic abuse. The presence of personality disorders in these patients is poorly documented, with the exception of neuroticism, which probably reflects the anxious and depressive comorbidity. Clinical findings show that a subgroup of patients needs an hospitalisation to succeed in withdrawal. They appears likely to be dependant on several types of drugs, to present with fear of pain itself, and to present with cluster B personality disorders, whereas another subgroup is specifically dependant on one type of drug, present with fear of pain induced impairement, and present with cluster C personality disorders. Those patients, when becoming aware of dependance, succeed in withdrawal at home, without the need of an hospitalization. The analgesic medication overuse and dependance can also be considered as a maladjusted strategy to manage pain (with prevalent passive and avoidant coping strategies). More research is required focusing on psychopathological aspects of analgesic overuse and dependance, to improve withdrawal modalities and to reduce the rate of relapses.

Abstract
Empirical studies of psychopathology are typically conducted in the goal of uncovering general characteristics of large samples of individuals. By contrast, the case study has remained a basic paradigm for understanding the causes of psychopathology as it is actually experienced by a given patient. However, by using case studies as an example, empirical researchers are rediscovering the importance of the individual. New data collection and analytic techniques have recently been applied to this effort, and considerable progress has been made to remove previous barriers to idiographic analyses. The present article describes these new applications, and discusses how empirical research can benefit from using case studies as a model for understanding the individual in a larger sample.

Abstract
OBJECTIVE The purpose of this study was to evaluate the outcome of bipolar disorder in the context of maintenance pharmacotherapy. METHOD Eighty-two bipolar outpatients were followed prospectively for a mean of 4.3 years (minimum of 2 years); symptom rating and psychosocial outcome scales were used, and pharmacotherapy was rated on a 5-point scale. RESULTS Despite continual maintenance treatment, survival analysis indicated a 5-year risk of relapse into mania or depression of 73%. Of those who relapsed, two-thirds had multiple relapses. Relapse could not be attributed to inadequate medication. Even for those who did not relapse, considerable affective morbidity was observed. A measure of cumulative affective morbidity appeared to be a more sensitive correlate of psychosocial functioning than was the number of relapses. Poor psychosocial outcome paralleled poor syndromal course. Poor psychosocial functioning, especially occupational disruption, predicted a shorter time to relapse. Depressions were most strongly related to social and family dysfunction. CONCLUSIONS Even aggressive pharmacological maintenance treatment does not prevent relatively poor outcome in a significant number of bipolar patients.

Abstract
OBJECTIVE The authors examined individual differences in stress reactivity as well as whether features of the illness itself or psychological characteristics differentiate between patients with bipolar disorder who are highly stress reactive and those who are not. METHOD They assessed stressors and bipolar episodes in 58 patients with bipolar disorder followed for at least 1 year. RESULTS Not only did stress level predict relapse, so did personality variables such as introversion and obsessionality and their interaction with stress. Number of previous episodes of bipolar illness, however, did not affect stress response. CONCLUSIONS These results are not consistent with the view that episodes of bipolar disorder become increasingly independent of stressors after initial episodes. However, psychological traits may affect reactivity to stressors.
