Depressive symptoms and history of depression predict rehabilitation efficiency in stroke patients.

OBJECTIVE: To examine how depressive symptoms, a history of depression, and cognitive functioning contribute to the prediction of rehabilitation efficiency in stroke patients. DESIGN: Consecutive admissions to an acute inpatient rehabilitation program were screened for cognitive functioning and level of depressive symptoms. History of depression was determined by family member interview. Functional status was evaluated at time of admission and discharge. Depressive symptoms, depression history, and cognitive functioning were examined as predictors of length of stay (LOS) and efficiency of utilization of rehabilitation services. SETTING: Acute inpatient rehabilitation hospital. PATIENTS: A total of 348 consecutive stroke admissions to an inpatient program were evaluated for depression and cognitive functioning, of whom 243 patients completed all aspects of the screening. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Rehabilitation progress, measured with the LOS efficiency measure (LOS-EFF) of the FIM instrument, and length of rehabilitation hospital stay. RESULTS: Patients with higher levels of depressive symptoms used rehabilitation services less efficiently than those with lower symptom levels but did not have longer LOSs. History of depression was associated with longer LOS and less efficient use of rehabilitation services. Cognitive impairment did not predict rehabilitation efficiency. CONCLUSIONS: The present study lends further support to the benefits of screening stroke patients at the time of rehabilitation admission for depression and history of depression. Identifying patients who have high levels of depressive symptoms and/or a previous depressive episode will allow more comprehensive assessment and rapid intervention.

Examinations of chronic pain and affect relationships: applications of a dynamic model of affect.

Two studies of the relationship between pain and negative affect are presented in this article: a study of weekly fluctuations in pain and negative affect among those with arthritis and a study of daily fluctuations in pain and negative affect for participants with fibromyalgia. The roles of positive affect and mood clarity (or the ability to distinguish between different emotions) in modifying the size of the relationship between pain and negative affect were examined in both studies as a means of testing the predictions of a dynamic model of affect regulation. In both studies, the presence of positive affect reduced the size of the relationship between pain and negative affect. Also, for arthritis participants with greater mood clarity, there was less overlap in ratings of negative and positive affective states.

Women's pursuit of personal goals in daily life with fibromyalgia: a value-expectancy analysis.

Eighty-nine women with fibromyalgia completed the Life Orientation Test, identified health and social goals, and answered questions from the Goal Systems Assessment Battery (P. Karoly & L. Ruehlman, 1995) about their valuation of, and self-efficiency in attaining, each goal. For 30 days, they responded to palm-top computer interviews about their pain and fatigue and rated their goal effort, goal progress, and pain- and fatigue-related goal barriers. Goal barriers increased and goal efforts and progress decreased on days with greater pain and fatigue; goals valued more highly were pursued more effortfully and successfully; more optimistic individuals were less likely to perceive goal barriers and, on days that were more fatiguing than usual, were less likely to reduce their effort and to retreat from progress in achieving their health goal; and more pessimistic individuals perceived greater goal barriers on days that were less painful than usual.

Daily interpersonal experiences, context, and alcohol consumption: crying in your beer and toasting good times.

The authors explored a multidimensional view of drinking, whereby social and solitary drinking represent distinct behaviors associated with positive and negative experiences, respectively. Using daily diary methodology and multilevel analytic strategy, the authors examined, over 30 days, the within-person association of negative and positive experiences and alcohol consumption in different contexts and focused on interpersonal experiences. On days with more negative interpersonal experiences, participants engaged in more solitary drinking (i.e., drinking at home and alone), whereas on days with more positive interpersonal experiences they drank more in social contexts. The authors also demonstrated that individuals high on neuroticism drank more in solitary contexts on days with more negative interpersonal experiences, relative to those with lower neuroticism. These findings lend support to models linking daily drinking motivation and context-dependent drinking behavior.

Living with rheumatoid arthritis: the role of daily spirituality and daily religious and spiritual coping.

The objective of this preliminary study was to evaluate more fully the role of daily spiritual experiences and daily religious/spiritual coping in the experience of individuals with pain due to rheumatoid arthritis (RA). Thirty-five individuals with RA were asked to keep a structured daily diary for 30 consecutive days. The diary included standardized measures designed to assess spiritual experiences, religious and spiritual pain coping, salience of religion in coping, religious/spiritual coping efficacy, pain, mood, and perceived social support. The participants in this study reported having spiritual experiences, such as feeling touched by the beauty of creation or feeling a desire to be closer or in union with God, on a relatively frequent basis. These participants also reported using positive religious and spiritual coping strategies much more frequently than negative religious and spiritual coping strategies. Although most of the variance in these measures was due to differences between persons, each measure also displayed a significant variability in scores from day to day. Indeed, there was just as much (or more) variability in these measures over time as there was variability in pain. Individuals who reported frequent daily spiritual experiences had higher levels of positive mood, lower levels of daily negative mood, and higher levels of each of the social support domains. Individuals who reported that religion was very salient in their coping with pain reported much higher levels of instrumental, emotional, arthritis-related, and general social support. Coping efficacy was significantly related to pain, mood, and social support in that on days that participants rated their ability to control pain and decrease pain using spiritual/religious coping methods as high, they were much less likely to have joint pain and negative mood and much more likely to have positive mood and higher levels of general social support. Taken together, these results suggest that daily spiritual experiences and daily religious/spiritual coping variables are important in understanding the experience of persons who have RA. They also suggest that newly developed daily diary methods may provide a useful methodology for studying religious and spiritual dimensions of living with arthritis.

Positive and negative daily events, perceived stress, and alcohol use: a diary study.

Using daily diary methodology, the authors examined over 60 days the within-person associations among positive and negative daily experiences, perceptions of stress, desire to drink, and alcohol consumption in a sample of 83 regular drinkers. Multilevel regression analyses indicated that days on which individuals reported more positive and negative nonwork events were also days they reported higher levels of desire to drink and actual consumption. Days on which individuals reported more negative work events were also days they reported a greater desire to drink, and days on which individuals reported more positive and negative health events were also days they reported lower levels of desire to drink and actual consumption. Weak evidence was found for the mediating effects of perceived stress in these associations. Several of the within-person associations varied as a function of gender, neuroticism, and drinking to cope; no moderating effects were found for extraversion.

The relationship of daily mood and stressful events to symptoms in juvenile rheumatic disease.

OBJECTIVES: The purpose of this study was 3-fold: 1) to assess the feasibility of a daily diary for use with children with juvenile rheumatic disease (JRD), 2) to describe daily variation in mood, stressful events, and symptoms in children with JRD, and 3) to examine the extent to which daily mood and daily stressful events predict daily symptoms in children with JRD. METHODS: Twelve children with JRD completed a daily booklet for 7 days. The daily booklet included measures of daily mood, daily stressful events, daily symptoms, and daily function. The children also completed a visual analog scale for pain and the Children's Depression Inventory. RESULTS: Subjects showed good compliance with scheduled completion and return of the daily diaries. Results indicated that children with JRD showed variability in daily mood, frequency of daily stressful events, and daily symptoms across days. Multilevel fixed effects models showed that more negative daily mood and more daily stressful events significantly predicted increased reports of fatigue, stiffness, and cutting back on daily activities. Negative daily mood also correlated with increases in daily reported pain. CONCLUSIONS: These results indicate that daily diary research is both feasible and potentially informative in children with JRD. Our data emphasize the need for further investigation into the role of daily mood and daily stressful events on disease course in JRD.

A daily process approach to coping. Linking theory, research, and practice.

For decades, coping researchers have used between-person designs to address inherently within-person questions derived from theory and clinical practice. The authors describe recent developments in the use of within-person, process-oriented methods that examine individuals intensively over time. Ongoing studies of stress and alcohol consumption, the effects of depression on adaptational processes, and the temporal dynamics of coping with chronic pain demonstrate that by tracking rapidly fluctuating processes such as mood and coping close to their real-time occurrence, daily process designs offer unique insights into conceptually and clinically challenging questions. Such designs also provide new opportunities to examine the purported mechanisms of therapeutic interventions. Despite its demands on participants and investigators, daily process research offers fresh opportunities to link psychological theory, research, and practice.

Mood and alcohol consumption: an experience sampling test of the self-medication hypothesis.

In this investigation the authors applied the experience sampling method to prospectively test the self-medication hypothesis. In vivo reports gathered in the context of daily life demonstrated that nervousness was the only negative mood state to predict increases in alcohol consumption later in the course of the day. Further examination of this within-person relationship demonstrated that men were more likely to consume alcohol when nervous than were women, but this association was unrelated to family history of alcoholism, problem drinking patterns, or trait anxiety and depression. Consistent with the self-medication hypothesis, cross-sectional analyses also confirmed that alcohol consumption was generally associated with lower levels of nervousness; this effect varied by several demographic and clinical variables. These findings are discussed in terms of the diversity of reasons for alcohol consumption and their potential for explaining problem drinking.

Stress and alcohol use: a daily process examination of the stressor-vulnerability model.

The authors used a daily diary methodology to examine over 60 days how the within-person associations among event stress, alcohol consumption, and desire to drink varied as a function of gender, positive and negative alcohol-outcome expectancies, and avoidant coping in a sample of 88 regular drinkers. Multilevel regression analyses indicated that men who more strongly anticipated positive outcomes or a sense of carelessness from drinking drank relatively more on stressful days compared with low-stress days. Similar results were found predicting desire to drink. Men who anticipated greater impairment from drinking drank relatively less on stressful days. In general, these effects did not hold for women. Little evidence was found for the predicted effects for avoidant coping style, and some results showed that avoidant coping style buffered the exacerbating effects of careless unconcern expectancies.

Mood states associated with transitory changes in asthma symptoms and peak expiratory flow.

OBJECTIVE: This study examined the within-person relations between transitory changes in mood, asthma symptoms, and peak expiratory flow rate (PEFR). METHODS: Thrice-daily for 21 consecutive days, 48 adults with moderate to severe asthma entered information in palm-top computers about their mood and asthma symptoms. A multidimensional model of mood, ie, the mood circumplex, informed the assessment of mood arousal and mood pleasantness. At each observation, participants also recorded their PEFR with peak flow meters that stored blinded data. Albuterol doses were also monitored electronically. Before and after the 21-day study, spirometric measures of airways obstruction were taken under controlled conditions. RESULTS: Random effects regression models revealed a significant, but weak, within-person relation between symptoms and PEFR. Changes in mood vectors with an arousal component were significantly related to PEFR changes, whereas changes in mood vectors with a pleasantness component tracked changes in asthma symptom reports, even after adjustment for contemporaneous PEFR and after controlling for time of day and albuterol dosing. Comparison of spirometric assessments with unsupervised PEFR suggested that part of the relation between mood arousal and PEFR may be attributable to the "effort-dependence" of peak flow self-monitoring. CONCLUSIONS: Different dimensions of mood were associated with transitory changes in asthma symptoms and PEFR. This may be one reason why individuals with asthma misperceive the severity of their symptoms in relation to underlying airways obstruction.

Does affect mediate the association between daily events and alcohol use?

OBJECTIVE: We examined the within-person associations among positive and negative daily events, positive and negative affect, desire to drink, and alcohol consumption in a sample of heavy drinkers. METHOD: Forty-six subjects (25 men; mean [SD] age = 47.0 [9.3] years) who were enrolled in an 8-week treatment program for heavy drinkers were studied using a daily diary methodology. RESULTS: Multilevel regression analyses indicated that individuals reported stronger desire to drink and greater consumption on days in which more positive and negative nonwork events occurred. Lower levels of desire to drink and number of drinks were reported on days with more positive work events. Negative work events had a marginal positive association with daily desire to drink. Daily positive and negative affect uniquely predicted greater daily consumption and desire to drink, but only weak evidence was found for their mediating role in the association between daily events and the criterion variables. Several of the within-person associations among affect and the criterion variables varied as a function of number of lifetime symptoms of alcohol dependence and treatment condition. CONCLUSIONS: These findings generally support the dual-process (i.e., tension-reduction and experience-enhancement) motivational model of alcohol consumption. However, the observed associations among events, affect and alcohol-related behavior suggests that these pathways are complex, with each being comprised of affective and cognitive subpathways.

Multilevel daily process designs for consulting and clinical psychology: a preface for the perplexed.

The next 3 articles in this issue use multilevel statistical procedures to analyze data collected in daily process studies of (a) stress and coping, (b) binge eating, and (c) chronic pain experience. Important differences in the methods and procedures of these studies illustrate the many options available to investigators and data analysts. This article serves as a preface to help readers who are new to these studies' methodology appreciate their novel contributions to the literature in consulting and clinical psychology. Four frequently asked questions are addressed concerning the design of daily process studies, the distinctive meaning of a within-person finding, the possibility that self-monitoring studies are measurement reactive, and complexities in the use of multilevel statistical procedures for analyzing person-day data sets.

Rheumatoid arthritis patients show weather sensitivity in daily life, but the relationship is not clinically significant.

While the majority of rheumatoid arthritis (RA) patients report that their pain is influenced by the weather, studies examining the impact of weather on RA pain have yielded equivocal results. It is not clear from the existing studies if the mixed results are due to limited statistical power (e.g. small sample sizes and restricted variability in weather indices) or the failure to consider individual differences. The current study addressed these weaknesses by having 75 RA patients (mean age = 52.7; 71% female) record their daily pain severity for 75 consecutive days. Objective weather indices including temperature, barometric pressure, relative humidity, and percentage of sunlight were obtained for the same dates from a local weather service. The results indicate that for the entire sample, pain levels were highest on cold, overcast days and following days with high barometric pressure. Pain levels also increased as a function of change in relative humidity from one day to the next. Individual difference analyses revealed significant variability between patients in their weather sensitivity patterns. In general, patients with higher levels of self-reported pain demonstrated more weather sensitivity. When considering the magnitude of these effects, however, weather variables accounted for only a small amount of change in pain scores. This pattern was true even for patients with the most pronounced pain-weather relationships. Thus, although weather sensitivity was found, the effect sizes were not clinically meaningful.

The relationship of arthritis self-efficacy to daily pain, daily mood, and daily pain coping in rheumatoid arthritis patients.

There is an increasing awareness in the medical community that psychosocial variables such as beliefs in self-efficacy are important determinants of treatment outcome. However, before measures of self-efficacy are widely incorporated into clinical practice, there needs to be a better understanding of how they relate to daily pain, mood and coping. In the present study 128 rheumatoid arthritis patients completed diaries for 30 days in which they provided daily ratings of joint pain, negative and positive mood, the use of pain coping strategies, and coping efficacy. The patients then participated in an evaluation session during which measures of self-efficacy (the Arthritis Self Efficacy Scale (ASES)), demographic variables, and medical status were collected. A series of hierarchical regression analyses was conducted to determine the degree to which self-efficacy measures collected at the time of the evaluation session were related to daily diary measures collected during the 30 preceding days. The results revealed that self-efficacy was significantly related to daily ratings of pain, mood, coping and coping efficacy. Interestingly, the findings regarding self-efficacy were obtained even after taking into account the effects of important demographic and medical status variables. Taken together, these results suggest that self-efficacy ratings collected from arthritis patients at the time of an evaluation session may well be related to recent experiences of daily pain and mood, as well as the daily use and perceived effectiveness of pain coping strategies.

The influence of demographic and socioeconomic factors on health-related quality of life in asthma.

BACKGROUND: Although health-related quality of life (HRQL) in asthma is strongly influenced by disease severity, demographic and socioeconomic variables may also be important factors. OBJECTIVE: We related demographics, asthma severity, and socioeconomic factors to HRQL. METHODS: We interviewed 50 patients with moderate or severe asthma recruited from outpatient health center-based clinics to determine demographics, socioeconomic status, asthma severity, medication use, and HRQL. For HRQL, the mean total score of the Asthma Quality of Life Questionnaire (AQLQ) and the Medical Outcomes Study Short-Form 36 questionnaires physical and mental component summary scores (PCS and MCS, respectively) were used. RESULTS: The mean patient age was 46 +/- 14 years, and the FEV1 was 75% +/- 21% of predicted value. Twenty-nine subjects had been hospitalized for asthma, 29 belonged to a minority racial/ethnic group, and 16 had less than 12 years of education. The mean total AQLQ score was 4.12 +/- 1.42, the PCS was 37 +/- 10, and the MCS was 45 +/- 13. In univariate analyses, severity (nighttime awakenings, prednisone use, and a history of emergency department visits), racial/ethnic group (African American, white, or Hispanic), and socioeconomic status (low educational level, unemployed, family income under $20,000, public assistance, or no health insurance) were related to HRQL. These factors explained 67% of the variance of AQLQ and 48% of the variance of the PCS. Much of the quality of life variance was shared among these variables. Explanatory variables were not related to MCS in multivariate analysis. CONCLUSION: Socioeconomic status is an additional important independent factor influencing HRQL in asthma. In this study it was difficult to separate out the unique effects of socioeconomic status and race/ethnicity.

Screening for depression in stroke: relationship to rehabilitation efficiency.

Depression is common after stroke but is often not diagnosed. Its presence may impair progress during rehabilitation and limit functional improvement after discharge. We investigated the use of the Geriatric Depression Scale (GDS) to screen for depression among acute stroke patients. All stroke patients in an acute rehabilitation hospital who were referred for assessment of cognitive deficits were also screened for depression with the GDS. By using a modified cutoff score to account for items that could reflect physical effects of the stroke rather than depression, 22% of patients screened were classified as depressed. The rate of depression was higher among women (36%) than men (10%). Patients with elevated GDS scores (> or =15) stayed in the hospital an average of 5.76 days longer than patients whose scores fell below this cut-off. Higher GDS scores were also associated with less efficient use of rehabilitation services as measured by the Functional Independence Measure. Screening stroke patients for depression at the time of admission to rehabilitation may identify individuals at risk to progress more slowly, may initiate more comprehensive assessment, and, if appropriate, may initiate rapid intervention.

Levels and patterns of alcohol consumption using timeline follow-back, daily diaries and real-time "electronic interviews".

OBJECTIVE: This study was designed to compare the Timeline Follow-Back (TLFB) to daily and real-time assessments of drinking. Our purpose was to evaluate overall correspondence and day-to-day agreement between these two methods among both problem and moderate drinkers. METHOD: In Study 1, problem drinkers (n = 20) reported their alcohol consumption daily during 28 days of brief treatment. In Study 2, moderate drinkers (n = 48), recruited from the community, used a palm-top computer to record their drinking for 30 days. In both studies participants completed the TLFB covering the recording period. RESULTS: Participants in Study 1 reported fewer drinking days, fewer drinks per drinking day and fewer total drinks per day on the TLFB, and those in Study 2 reported fewer drinks per drinking day, fewer ounces per drinking day, fewer total drinks per day and fewer total ounces per day. The magnitude of the difference, however, was modest. There was considerable between-person variation in day-to-day correspondence of TLFB and the daily and real-time reports. Neither person characteristics (gender, education and income) nor the distributional characteristics of drinking (including average consumption, variation) predicted concordance between TLFB and real-time reports. CONCLUSIONS: The Timeline Follow-Back method captured overall levels of drinking quite well compared to a 28-day daily diary and a 30-day electronic interview. Vast individual differences in day-to-day correspondence suggest that the TLFB may be less useful for detecting patterns of consumption.

Distress, depressive symptoms, and depressive disorder among caregivers of patients with brain injury.

OBJECTIVE: To examine the prevalence and correlates of major depression in caregivers of individuals with moderate to severe traumatic brain injuries. DESIGN: Repeated-measures design involving structured diagnostic interview and self-report of psychological distress administered on two occasions separated by 6 months. SETTING: Three acute care rehabilitation hospitals. SUBJECTS: Fifty-nine caregivers (39 mothers and 20 spouses) of individuals with moderate to severe brain injuries recruited from previous inpatient rosters. All caregivers were currently residing with the person with traumatic brain injury. MAIN OUTCOME MEASURE: The Diagnostic Interview Schedule-Revised [DIS-R] was utilized to assess depression. The Symptom Checklist 90-Revised (SCL 90-R) measured general psychological distress. RESULTS: Forty-seven percent of caregivers initially met diagnostic criteria for depression, and 43% met criteria 6 months later. Nearly two thirds of those who were initially depressed continued to be depressed 6 months later, and 17% of those who were not depressed initially subsequently met criteria for depression. The best predictor of depression was a previous (pre-brain injury) depressive episode. Neither time since injury nor injury severity predicted diagnostic status, and spouses were no more likely to be depressed than were mothers. The SCL 90-R, including its depression scale, showed high specificity but low sensitivity in predicting diagnostic status. CONCLUSIONS: The prevalence of major depression is high in caregivers of individuals with brain injuries. Because depression may interfere with the capacity to provide care and contribute to the rehabilitation process, it is important for clinicians to carefully assess both the current and preaccident affective status of primary caregivers.

Adherence with twice-daily dosing of inhaled steroids. Socioeconomic and health-belief differences.

Poor adherence to medication regimens may be contributing to the recent increase in asthma morbidity and mortality. We examined patient characteristics that may influence adherence to twice-daily inhaled steroid regimens. Fifty adults with moderate to severe asthma completed questionnaires examining sociodemographics, asthma severity, and health locus of control. Adherence was electronically monitored for 42 d. Following monitoring, patients' understanding of asthma pathophysiology and the function of inhaled corticosteroids were assessed. Patient beliefs about the effectiveness and convenience of these medications, and their perception of communications with their clinician were measured. Mean adherence was 63% +/- 38%; 54% of subjects recorded at least 70% of the prescribed number of inhaled-steroid actuations. Factors associated with poor adherence were less than 12 yr of formal education (p < 0. 001), poor patient-clinician communication (p < 0.001), household income less than $20,000 (p = 0.002), Spanish as primary language (p = 0.005), and minority status (p = 0.007). In a multiple logistic regression analysis, less than 12 yr of formal education (OR: 6.72; CI: 1.10 to 41.0) and poor patient-clinician communication (OR: 1.2; CI: 1.01 to 1.55) were independently associated with poor adherence. These results emphasize the importance of socioeconomic status and adequate patient-clinician communication for adherence to inhaled-steroid schedules.
