The feasibility of using ecological momentary assessment to understand urinary and fecal incontinence experiences in adults with spina bifida: A 30-day study

In this paper, we evaluate the feasibility of using ecological momentary assessment (EMA) to understand urinary (UI) and fecal (FI) incontinence in adults with spina bifida (SB). As part of a larger 30-day prospective study to understand the incontinence in adults with SB (N = 89), participants completed end-of-day EMA diaries assessing the frequency and context of UI and FI. We used these data to assess the method feasibility across six dimensions: (a) compliance, or data entry which is consistent with study protocol and substantially complete; (b) reactivity, or behavior change attributed to study participation; (c) participant acceptability, or convenience and ease of method beneficial to compliance; (d) data capture, or the volume of incontinence behaviors collected; (e) the accuracy of incontinence reports; and f) participant-provided feedback for future studies. Participants were highly compliant with diary entry protocol and schedule: submitting 95.7% (2576/2700) of the expected total daily entries. The average completion time was two minutes. Neither the total number of submissions nor the completion time varied by demographic characteristics or health history. A sufficient volume of incontinence and affective outcomes were captured, with small downtrends in reporting of UI and affect over time. Exit survey recall was highly correlated with diary reports. Participants found the methodology to be acceptable, reported their experiences honestly, enjoyed and felt comfortable participating in the study and would engage in similar study in the future. Accurate information about the daily context of UI and FI is a key factor in the success of intervention or education programs relying on this information. Our findings demonstrate that EMA is a feasible way to describe UI and FI in adults with SB.

Ecological Momentary Assessment: A Field Evaluation of Subjective Ratings of Speech in Noise

PURPOSE

As hearing rehabilitation research evolves to include both retrospective and momentary assessment outcome measures, it is important to understand how in-the-moment contextual factors influence subjective ratings. We aimed to determine, over a 4-week period of participants responding to ecological momentary assessments (EMAs) in their own environments, whether: (1) participants will complete surveys in speech-in-noise listening situations; (2) ratings of speech in noise change in a predictable manner as the acoustic conditions change; and (3) EMAs provide patient insights beyond those provided from retrospective ratings.

DESIGN

Fourteen adults aged 26 to 86 years with at least 6 months of hearing aid experience were recruited for an 8-week crossover field trial (4 weeks wearing hearing aids with no EMA; 4 weeks wearing hearing aids with EMA). Participants were fitted with hearing aids and provided with a streamer and a smartphone with an app that analyzed the acoustic signal from the hearing aids and alerted the participant to respond to a survey when predetermined acoustic conditions were detected. Participants were prompted to complete brief surveys up to 9 times/day that contained establishing questions, quality ratings, and items assessing perceived benefit, residual activity limitation, and satisfaction. Participants also completed retrospective questionnaires at intake and after each 4-week field trial.

RESULTS

Participants completed an average of 4.4 surveys per day. The quality ratings changed as the acoustics changed: Ratings of intelligibility were lower for 10 dB signal-to-noise ratio (SNR) than 20 dB SNR (p = 0.006); ratings of noisiness were higher for 10 dB SNR than 20 dB SNR (p = 0.001) and higher for 65 dB SPL than 50 dB SPL (p < 0.001); ratings of effort were higher for 65 dB SPL than 50 dB SPL (p = 0.004); ratings of loudness were higher for 65 dB SPL than 50 dB SPL (p = 0.001). Descriptive analysis of satisfaction, benefit, and residual activity limitation responses showed that the momentary surveys provided more detail about individual variability across acoustic conditions than the retrospective questions.

CONCLUSIONS

Participants completed more than 99% of the triggered surveys, demonstrating high compliance. Because the quality ratings generally changed in the hypothesized direction, it is concluded that the participants provided valid responses. The greater variability in responses with EMA than retrospective questionnaires demonstrates its potential utility as a clinical tool for exploring hearing aid outcomes in real-world environments.

Motives for Substance Use in Daily Life: A Systematic Review of Studies Using Ecological Momentary Assessment

The motivational model of substance use posits four motive subtypes (coping, enhancement, social, conformity) dynamically interact with contextual factors to impact decisions about substance use. Yet, prior studies assessing the motivational model have relied on between-person, cross-sectional evaluations of trait motives. We systematically reviewed ecological momentary assessments (EMA) studies (N=64) on motives for substance use to examine: methodological features of EMA studies examining the motivational model, support for the motivational model between and within individuals, and associations between trait motives and daily processes. Results of the reviewed studies provide equivocal support for the motivational model, and suggest that EMA measures and trait measures of motives might not reflect the same construct. The reviewed body of research indicates most studies have not examined the momentary and dynamic nature of the motivational model and more research is needed to inform interventions that address heterogeneous reasons for substance use in daily life.

Reported Affect Changes as a Function of Response Delay: Findings From a Pooled Dataset of Nine Experience Sampling Studies

Delayed responses are a common phenomenon in experience sampling studies. Yet no consensus exists on whether they should be excluded from the analysis or what the threshold for exclusion should be. Delayed responses could introduce bias, but previous investigations of systematic differences between delayed and timely responses have offered unclear results. To investigate differences as a function of delay, we conducted secondary analyses of nine paper and pencil based experience sampling studies including 1,528 individuals with different clinical statuses. In all participants, there were significant decreases in positive and increases in negative affect as a function of delay. In addition, delayed answers of participants without depression showed higher within-person variability and an initial strengthening in the relationships between contextual stress and affect. Participants with depression mostly showed the opposite pattern. Delayed responses seem qualitatively different from timely responses. Further research is needed to understand the mechanisms underlying these differences.

Meet the parents: Parental interactions, social influences, and college drinking

Previous research suggests that, even in college, parents influence the alcohol consumption of their children directly and indirectly through peers. However, research has not tested whether face-to-face interactions with parents buffer students against social influences on drinking. In the current study, 1168 undergraduate students selected 5 people they contact regularly and then completed a 30-day daily diary reporting on interactions with those people and drinking behavior. The 401 students who selected a parent drank less and less often than those who did not select a parent as a frequent contact. In addition, on evenings when these students had met with their parents, they drank less alcohol and the association between others' drinking and participant drinking was weakened. This adds to evidence suggesting that parents continue to influence emerging adults after they have left home and may be helpful in informing future intervention efforts.

The new normal: Changes in drinking norms from college to postcollege life

[Correction Notice: An Erratum for this article was reported in Vol 34(4) of Psychology of Addictive Behaviors (see record 2020-38542-001). In the article, the description of the prospective sample in the second sentence of the second paragraph and the second sentence of the third paragraph of the Participants section is incorrect. The description should appear, respectively, as follows: These were participants who were contacted if they reported at least one heavy drinking day (≥4 drinks for women and ≥5 drinks for men) in both a 30-day retrospective assessment and a 30-day daily diary reporting phase at Wave 1. . . . Of these, 1,141 were identified as moderate to heavy drinkers. Due to a coding error, 23 of these individuals did not meet these criteria but were contacted for Wave 2. However, all of these individuals reported drinking levels at Wave 1 (using a drinking composite comprised of standardized retrospective and daily diary drinking variables) within the range of values for the individuals who met the correct criteria. All were retained for analysis and 906 (79%) completed at least 15 days of recording in Wave 2.²] Despite the wealth of research on the effects of drinking norms on college students' alcohol consumption, researchers have not yet examined changes in drinking norms and their association with drinking level after students leave the college environment. The current study filled this gap by following students into postcollege life, measuring drinking norms and daily drinking behavior. College students (N = 1,848) were recruited to take part in a daily diary study measuring social and solitary alcohol consumption, and 1,142 moderate to heavy drinkers from the college cohort were invited to complete a second wave of daily diaries 5 years later, with 906 providing at least 15 days of diary data in each wave. Results of multilevel modeling analyses suggest that family injunctive drinking norms become more strongly related to alcohol consumption after individuals leave college. In contrast, institutional injunctive norms may have a greater limiting effect among college students (i.e., the association was greater among college students) and the relations between friend injunctive and descriptive norms to drinking behavior did not change between waves in the current study. This suggests that friend drinking continues to be related to own drinking behavior among adults after leaving the college environment, and highlights the changing importance of institutional norms and family approval. These results may have implications for intervening in young adults' heavy drinking. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Couples Adjusting to Multimorbidity: A Dyadic Study on Disclosure and Adjustment Disorder Symptoms

Background

Multimorbidity is challenging not only for the patient but also for the romantic partner. Strategies for interpersonal emotion regulation like disclosing to the partner are supposed to play a major role in the psychosocial adjustment to multimorbidity. Research has often focused on disease-related disclosure, even though disclosing thoughts and feelings related to mundane, everyday life occurrences might also play a role in coadjustment. The current dyadic study aimed at investigating the association between these two types of interpersonal regulation strategies and adjustment disorder symptoms, following the new ICD 11 criteria in multimorbid patients and their partners.

Methods

Shortly after being hospitalized due to an acute health crisis, N = 28 multimorbid patients (average age 70 years) and their partners filled in questionnaires on disclosure in the couple, adjustment disorder criteria of the ICD 11 (“preoccupation,” “failure to adapt”), and sleep problems.

Results

Both patients and their partners did show similarly high levels of preoccupation and failure to adapt indicating adjustment problems to the complex health situation. The adjustment symptoms of both partners correlated between r = 0.22 and 0.45. Regression based on Actor-Partner Interdependence-Models revealed that own mundane disclosure was related to less adjustment symptoms in the patients. Beyond that, a partner effect was observed, revealing a negative association between partners’ illness-related disclosure and the patients’ level of preoccupation. For the partners, mundane disclosure of the partner was associated with less preoccupation, failure to adapt, and reported sleep problems above and beyond own disclosure reports. Furthermore, there was an actor effect of disease-related disclosure on less sleep problems for the partners.

Conclusion

These results support an interpersonal view on adjustment processes to physical disease. Disclosure as a way of regulating the relationship and emotional responses might play a relevant role here, which seems to be different for patients and their partners. Further research is needed to shed more light on the differential role of disease-related and mundane everyday disclosure for psychosocial adjustment in couples confronted with health challenges.

Temporal Immediacy: A Two-System Theory of Mind for Understanding and Changing Health Behaviors

BACKGROUND

Health promotion and chronic disease management both require behavior change, but people find it hard to change behavior despite having good intentions. The problem arises because patients' narratives about experiences and intentions are filtered through memory and language. These narratives inaccurately reflect intuitive decision-making or actual behaviors.

OBJECTIVES

We propose a principle-temporal immediacy-as a moderator variable that explains which of two mental systems (narrative or intuitive) will be activated in any given situation. We reviewed multiple scientific areas to test temporal immediacy as an explanation for findings.

METHODS

In an iterative process, we used evidence from philosophy, cognitive neuroscience, behavioral economics, symptom science, and ecological momentary assessment to develop our theoretical perspective. These perspectives each suggest two cognitive systems that differ in their level of temporal immediacy: an intuitive system that produces behavior in response to everyday states and a narrative system that interprets and explains these experiences after the fact.

FINDINGS

Writers from Plato onward describe two competing influences on behavior-often with moral overtones. People tend to identify with the language-based narrative system and blame unhelpful results on the less accessible intuitive system, but neither is completely rational, and the intuitive system has strengths based on speed and serial processing. The systems differ based on temporal immediacy-the description of an experience as either "now" or "usually"-with the intuitive system generating behaviors automatically in real time and the narrative system producing beliefs about the past or future.

DISCUSSION

The principle of temporal immediacy is a tool to integrate nursing science with other disciplinary traditions and to improve research and practice. Interventions should build on each system's strengths, rather than treating the intuitive system as a barrier for the narrative system to overcome. Nursing researchers need to study the roles and effects of both systems.

Using Ecological Momentary Assessment (EMA) to Study Sex Events Among Very High-Risk Men Who Have Sex with Men (MSM)

MSM continue to represent the largest share of new HIV infections in the United States each year due to high infectivity associated with unprotected anal sex. Ecological momentary assessment (EMA) has the potential to provide a unique view of how high-risk sexual events occur in the real world and can impart detailed information about aspects of decision-making, antecedents, and consequences that accompany these events. EMA may also produce more accurate data on sexual behavior by assessing it soon after its occurrence. We conducted a study involving 12 high-risk MSM to explore the acceptability and feasibility of a 30 day, intensive EMA procedure. Results suggest this intensive assessment strategy was both acceptable and feasible to participants. All participants provided response rates to various assessments that approached or were in excess of their targets: 81.0 % of experience sampling assessments and 93.1 % of daily diary assessments were completed. However, comparing EMA reports with a Timeline Followback (TLFB) of the same 30 day period suggested that participants reported fewer sexual risk events on the TLFB compared to EMA, and reported a number of discrepancies about specific behaviors and partner characteristics across the two methods. Overall, results support the acceptability, feasibility, and utility of using EMA to understand sexual risk events among high-risk MSM. Findings also suggest that EMA and other intensive longitudinal assessment approaches could yield more accurate data about sex events.

Brief report on ecological momentary assessment: everyday states predict HIV prevention behaviors

Background

Prevention behaviors help persons living with HIV (PLWH) to avoid transmitting HIV, and psychological variables have been found to predict HIV prevention behaviors. These variables have typically been measured using retrospective questionnaires about average psychological states over a period of time, which are likely to be biased by selective recall and interpretation. Measuring the same variables as momentary states, in the day-to-day context where they actually occur, may reveal different relationships to behavior.

Findings

21 PLWH completed daily surveys about momentary states and prevention behaviors. Brief, validated measures were used to assess control beliefs, mood, stress, coping, social support, stigma, knowledge, and motivation. We used multilevel models to predict prevention behaviors from momentary states the previous day, while controlling for the effect of multiple observations from the same person over time. Participants reported a moderate overall level of HIV prevention behaviors during the 6-month study. Although lapses in prevention were infrequent, there was room for improvement. Control beliefs, mood, and motivation had significant prospective effects on HIV prevention behaviors, rs = 0.07−0.21. Stress and coping had effects approaching significance.

Conclusions

Some momentary states predicted prevention behaviors, providing partial support for the motivational model. This finding supports past research showing effects of momentary states on behavior, and advances the science by testing multiple predictors. High within-sample diversity strengthened generalizability, but the overall sample size was small and the findings require replication. Future research should continue to examine the everyday experiences of PLWH as influences on their behavior.

PTSD and Daily Co-Occurrence of Drug and Alcohol Use Among Women Experiencing Intimate Partner Violence

OBJECTIVE

People with posttraumatic stress disorder (PTSD) are at high risk for substance use, and PTSD is common among women experiencing intimate partner violence. Considering the effects of both PTSD and substance use, such as poorer treatment outcomes and greater health/behavior problems, women experiencing intimate partner violence are a high-risk, under-researched group.

METHODS

We utilized a micro-longitudinal study design to assess daily drug and alcohol use over 21 days among 41 women experiencing intimate partner violence recruited from the community.

RESULTS

Participants were about 45 years old (M = 45.1, SD = 8.5) and mostly African American (n = 32, 78%). Co-occurrence of drug and alcohol use was reported on 19.0% of days, while drug use alone occurred on 13.4% of days and alcohol use on 12.1%. Fifteen percent of participants met current PTSD criteria, with a mean symptom severity rating of 15.90 (SD = 10.94, range 0 to 47). Women with PTSD, compared to those without, were nearly 15 times more likely to have days of co-occurrence of drug and alcohol use (p = .037) and nearly 7 times more likely to have days of drug use alone (p = .044).

CONCLUSIONS

These findings indicate that the combination of intimate partner violence and PTSD may make women especially prone to daily co-occurring drug and alcohol use or drug use alone. Further research is needed to explore this association and examine the need for integrated programs to support victims' health, prevent the development of substance use problems, and facilitate recovery from PTSD and substance use.

Friendship Intimacy, Close Friend Drug Use, and Self-Medication in Adolescence

The current study examined between- and within-person processes related to friendship intimacy, close-friend substance use, negative affect, and self-medication. We tested between-person hypotheses that global negative affect, friendship intimacy, and close-friend drug use predict increased substance use, and the within-person hypothesis that friendship intimacy and close-friend substance use moderate the temporal relationship between daily negative affect and subsequent substance use (i.e., self-medication). Experience sampling methodology (ESM) was employed to capture daily variations in mood and substance use, and multilevel modeling techniques were used to parse between- versus within-person differences in risk for use. Findings supported between-person hypotheses that higher levels of negative affect and lower levels of friendship intimacy predicted greater substance use, and a consistent trend indicated that friendship intimacy and close-friend drug use interact to predict substance use more generally (though not for self-medication). Risk and protective mechanisms emerged from this interaction such that the effect of friendship intimacy on adolescent use depends on the degree of close-friend drug use. More specific reformulations of the risk processes involving friendships and self-medication among younger youth are indicated.

Comparison of text messaging and paper-and-pencil for ecological momentary assessment of food craving and intake

Electronic devices such as mobile phones are quickly becoming a popular way to gather participant reports of everyday thoughts, feelings, and behaviors, including food cravings and intake. Electronic devices offer a number of advantages over alternative methods such as paper-and-pencil (PNP) assessment including automated prompts, on-the-fly data transmission, and participant familiarity with and ownership of the devices. However, only a handful of studies have systematically compared compliance between electronic and PNP methods of ecological momentary assessment (EMA), and none have examined eating specifically. Existing comparisons generally find greater compliance for electronic devices than PNP, but there is variability in the results across studies that may be accounted for by differences across research domains. Here, we compared the two EMA methods in an unexamined domain - eating - in terms of response rate and response latency, and their sensitivity to individual difference variables such as body mass index (BMI). Forty-four participants were randomly assigned to report on their food craving, food intake, and hunger four times each day for 2 weeks using either a PNP diary (N = 19) or text messaging (TXT; N = 25). Response rates were higher for TXT than PNP (96% vs. 70%) and latencies were faster (29 min vs. 79 min), and response rate and latency were less influenced by BMI in the TXT condition than in the PNP condition. These results support the feasibility of using text messaging for EMA in the eating domain, and more broadly highlight the ways that research domain-specific considerations (e.g., the importance of response latency in measuring short-lived food craving) interact with assessment modality during EMA.

Anger as a predictor of psychological distress and self-harm ideation in inmates: a structured self-assessment diary study

Suicidal ideation and behaviour are common among inmates. Anger is found at exaggerated levels and has been associated with suicidal ideation and behaviour in inmate samples suggesting its possible salience in the prediction of suicide. The study investigated relationships between anger, psychological distress, and self-harm/suicidal ideation among inmates. The principles of Ecological Momentary Assessment were considered and a structured self-assessment diary was utilised to examine relationships between the variables of interest. Participants completed a structured self-assessment diary for six consecutive days which included momentary ratings of items describing psychological states of concurrent affects, thoughts, and appraisals related to anger, psychological distress, and self-harm/suicidal ideation. Psychometric assessment measures were also conducted. Temporal associations between predictors and outcomes were investigated. Multilevel modelling analyses were performed. Increased anger was significantly associated with concurrent high levels of self-harm ideation in inmates, when controlling for depression and hopelessness. Temporal analyses also revealed that anger at one time point did not predict suicidal ideation at the next time point. Elucidating the temporal nature of the relationship between anger, psychological distress, and self-harm/suicidal ideation has advanced understanding of the mechanisms of suicidal behaviour, by demonstrating an increased risk of suicide when a male inmate is angry.

Predictors of adherence to home rehabilitation exercises following anterior cruciate ligament reconstruction

OBJECTIVE

Although home exercises are commonly prescribed following anterior cruciate ligament (ACL) reconstruction and are considered important in obtaining successful rehabilitation outcomes, little is known about factors associated with the completion of such exercises. Consequently, this study was designed to identify predictors of adherence to home rehabilitation exercises after ACL surgery.

METHOD

Participants (33 women, 58 men) completed indices of athletic identity, neuroticism, optimism, and pessimism before ACL surgery and measures of daily pain, negative mood, stress, and home exercise completion for 42 days postoperatively.

RESULTS

Participants reported a high level of adherence to the prescribed regimen. Home exercise completion increased significantly over time as the number of sets of prescribed home exercises declined. Personal factors were not predictive of home exercise completion. Participants completed fewer home exercises on days when they experienced more stress or negative mood.

CONCLUSIONS

Day-to-day variations in negative mood and stress may contribute to adherence to prescribed home exercises.

How to Investigate Within-Subject Associations between Physical Activity and Momentary Affective States in Everyday Life: A Position Statement Based on a Literature Overview

Several meta-analyses have investigated the association between physical activity and affective states and have found evidence suggesting that exercise exerts a positive effect on affective state. However, in this field of research, most studies have conducted between-subject analyses. Nonetheless, there is more and more interest in the within-subject associations between physical activity and momentary affective states in everyday life. This position statement pertains to this up-and-coming field of research and provides methodological recommendations for further studies. The paper is divided into three parts: first, we summarize and evaluate three methodological requirements necessary for the proper evaluation of within-subject associations between physical activity and momentary affective states in everyday life. We propose that the following issues should be considered: (a) to address the dynamic nature of such relationships, repeated assessments are necessary; (b) as activities performed in everyday life are mostly spontaneous and unconscious, an objective assessment of physical activity is useful; (c) given that recall of affective states is often affected by systematic distortions, real-time assessment is preferable. In sum, we suggest the use of ambulatory assessment techniques, and more specifically the combination of accelerometer-assessment of physical activity with an electronic diary assessment of the momentary affective state and additional context information. Second, we summarize 22 empirical studies published between 1980 and 2012 using ambulatory assessment to investigate within-subject associations between momentary affective states and physical activity in everyday life. Generally, the literature overview detects a positive association, which appears stronger among those studies that were of high methodological quality. Third, we propose the use of ambulatory assessment intervention (AAIs) strategies to change people’s behavior and to enable people to be active as often as possible during the day (e.g., reducing sitting time, taking more steps per day).

Electronic Diaries: Appraisal and Current Status

The recent explosion of technology has moved the field of patient reported outcomes (PROs) into a new era. Use of paper-and-pencil questionnaires administered before and after treatment has been eclipsed by highly sophisticated random prompts for symptom ratings at multiple points throughout the day, a method known as ecological momentary assessment (EMA). During the last 25 years, research has demonstrated that retrospective ratings are subject to a variety of cognitive heuristics that can distort the report. Initially, this was addressed by adopting paper diary protocols involving multiple ratings in a day or across a week. Technology was also advancing, and some researchers began to utilize electronic platforms for EMA assessment. A good deal of research has been conducted comparing paper and electronic formats. Issues of compliance have been particularly problematic for paper diaries. Electronic technologies can be expensive and require expertise in programming and data management. Not all research questions will require intensive momentary assessment, and end-of-day ratings may be adequate for many applications. What is required of the investigator is familiarity with the strengths and weaknesses of the methods and platforms available as well as a reasoned decision to elect a particular methodology for the study question at hand.

Association between interactive voice response adherence and subject retention in a randomized controlled trial

INTRODUCTION

Interactive voice response (IVR) technology uses the telephone to collect patient reports. This study examined whether IVR adherence during a year-long clinical trial was related to subject retention in the trial.

METHODS

As part of a randomized, double-blind, placebo-controlled study of daily multivitamin supplementation for recurrent aphthous stomatitis, 160 study participants were asked to make 1 weekly IVR call for the one-year study duration.

RESULTS

The 114 subjects who completed the study made 90.5% of their expected number of IVR calls, as compared to 55.7% of expected calls made by the 46 subjects who withdrew prematurely (p<0.001). Subjects who successfully completed the study were also more likely to initiate their IVR calls as compared to subjects who withdrew from the study (p<0.001). A multivariable model incorporating different adherence variables was able to successfully predict retention status of more than 80% of subjects. IVR adherence during the first few weeks of study participation was strongly predictive of subsequent retention and successful completion of this one-year study.

DISCUSSION

Subjects who withdrew prematurely had more missing data than study completers, even after accounting for period of study participation, potentially introducing bias into IVR results. Sub-optimal adherence to weekly IVR might provide an early signal of subsequent premature withdrawal in clinical trials. IVR adherence could be used as a screening tool during a trial period, to identify subjects most likely to stay on long clinical trials.

CONCLUSION

IVR adherence may be useful in anticipating retention in long-term clinical studies.

The feasibility of cell phone based electronic diaries for STI/HIV research

BACKGROUND

Self-reports of sensitive, socially stigmatized or illegal behavior are common in STI/HIV research, but can raise challenges in terms of data reliability and validity. The use of electronic data collection tools, including ecological momentary assessment (EMA), can increase the accuracy of this information by allowing a participant to self-administer a survey or diary entry, in their own environment, as close to the occurrence of the behavior as possible. In this paper, we evaluate the feasibility of using cell phone-based EMA as a tool for understanding sexual risk and STI among adult men and women.

METHODS

As part of a larger prospective clinical study on sexual risk behavior and incident STI in clinically recruited adult men and women, using study-provided cell phones, participants (N = 243) completed thrice-daily EMA diaries monitoring individual and partner-specific emotional attributes, non-sexual activities, non-coital or coital sexual behaviors, and contraceptive behaviors. Using these data, we assess feasibility in terms of participant compliance, behavior reactivity, general method acceptability and method efficacy for capturing behaviors.

RESULTS

Participants were highly compliant with diary entry protocol and schedule: over the entire 12 study weeks, participants submitted 89.7% (54,914/61,236) of the expected diary entries, with an average of 18.86 of the 21 expected diaries (85.7%) each week. Submission did not differ substantially across gender, race/ethnicity and baseline sexually transmitted infection status. A sufficient volume and range of sexual behaviors were captured, with reporting trends in different legal and illegal behaviors showing small variation over time. Participants found the methodology to be acceptable, enjoyed and felt comfortable participating in the study.

CONCLUSION

Achieving the correct medium of data collection can drastically improve, or degrade, the timeliness and quality of an individual's self-reported sexual risk behavior, which in turn, is a key factor in the success of intervention or education programs relying on this information. Our findings demonstrate that completion of electronic diaries via cellular phone is feasible way to describe STI/HIV risk among clinically recruited adult men and women.

Continuous glucose monitoring: a review for behavioral researchers

OBJECTIVE

Continuous glucose monitoring (CGM) systems collect and store glucose data in an ongoing fashion for several days at a time. The main advantage of CGM is that it can help identify fluctuations and trends that would otherwise go unnoticed with other glucose measures. Here, we provide a review of CGM for behavioral researchers.

METHODS

We begin with a brief review of diabetes and glucose measurement and then describe what CGM is and reference the commercial CGM systems currently available. We discuss the challenges involved in using CGM in behavioral research. We then present a broad overview of CGM in behavioral research, including data from ours and others' research programs. Finally, we cover some practical issues to be considered when using CGM, suggest reporting guidelines for the behavioral researcher, and offer suggestions for future research.

RESULTS

Only a handful of behavioral researchers are using CGM, although its use is increasing. The main ways that CGM is being used in behavioral research is to investigate basic biobehavioral processes, to assess the effects of behavioral interventions on diabetes control, and to use CGM itself as a behavior modification and teaching tool in diabetes self-management interventions.

CONCLUSIONS

Continuous glucose monitoring holds promise to help behavioral researchers unravel the complex relationships among glucose and intrapersonal, interpersonal, and contextual factors. However, the uptake of CGM for this purpose is limited, and the possibilities for its use are largely unmet. We encourage behavioral researchers to implement CGM in their protocols and to do so in a way that maximizes its explanatory power.

Understanding phenomena in the real world: the case for real time data collection in health services research

Understanding the environmental and behavioural predictors of wellbeing is a key driver of health and social care research. Research set in the social world examines the relationships between behavioural, cognitive, emotional and environmental factors, linking these to disease or social ills with the aim of providing better preventive or treatment services. Much of this research is based on retrospective measurement tools, such as questionnaires or interviews. However, retrospective accounts are prone to bias arising from the influence of the participant's current affective state on autobiographical memory and error-inducing heuristic strategies related to memory. Participant introspection also biases self-reports of behaviour and symptoms. This essay offers a critical examination of the advantages of ecological momentary assessment (EMA) methods over retrospective accounts in understanding social phenomena. Advantages of EMA include collection of longitudinal data from a representative part of the participant's daily experience, in real time and in the participant's natural environment. EMA accounts are gathered more closely in time to the event and are less biased by heuristic, autobiographical memory strategies. Real-time longitudinal data may be combined from a range of devices or forms of data collection; for example, self-report can be linked with objective physiological data. EMA allows testing of within-person variation in variables of interest in a way that is difficult to achieve using retrospective measures and between-person (group level) designs. EMA approaches provide not just more data, but better data than previously, allowing the application of more powerful analytic techniques to critical, real life questions than ever before.

Daily Cognitive Appraisals, Daily Affect, and Long-Term Depressive Symptoms: The Role of Self-Esteem and Self-Concept Clarity in the Stress Process

The current study investigated how self-esteem and self-concept clarity are implicated in the stress process both in the short and long term. Initial and 2-year follow-up interviews were completed by 178 participants from stepfamily unions. In twice-daily structured diaries over 7 days, participants reported their main family stressor, cognitive appraisals (perceived stressor threat and stressor controllability), and negative affect. Results of multilevel modeling indicated that high self-esteem ameliorated the effect of daily negative cognitive appraisals on daily negative affect. Self-concept clarity also buffered the effect of low self-self-esteem on depressive symptoms 2 years later. Our findings point to the vulnerability of those having low self-esteem or low self-concept clarity in terms of both short- and long-term adaptation to stress. They indicate the need for the consideration of such individual differences in designing stress management interventions.

A Comparison of Affect Ratings Obtained with Ecological Momentary Assessment and the Day Reconstruction Method

Measurement of affective states in everyday life is of fundamental importance in many types of quality of life, health, and psychological research. Ecological momentary assessment (EMA) is the recognized method of choice, but the respondent burden can be high. The day reconstruction method (DRM) was developed by Kahneman and colleagues (Science, 2004, 306, 1776-1780) to assess affect, activities and time use in everyday life. We sought to validate DRM affect ratings by comparison with contemporaneous EMA ratings in a sample of 94 working women monitored over work and leisure days. Six EMA ratings of happiness, tiredness, stress, and anger/frustration were obtained over each 24 h period, and were compared with DRM ratings for the same hour, recorded retrospectively at the end of the day. Similar profiles of affect intensity were recorded with the two techniques. The between-person correlations adjusted for attenuation ranged from 0.58 (stress, working day) to 0.90 (happiness, leisure day). The strength of associations was not related to age, educational attainment, or depressed mood. We conclude that the DRM provides reasonably reliable estimates both of the intensity of affect and variations in affect over the day, so is a valuable instrument for the measurement of everyday experience in health and social research.

Electronic and paper diary recording of infant and caregiver behaviors

OBJECTIVES

To assess (1) preference of parental use of an electronic diary (e-diary) over a paper diary to record continuous infant and caregiver behaviors over 7 days; (2) whether e-diary recordings would differ in systematic ways from those obtained by paper diaries, and (3) frequency of diary entries when parents provide entries when convenient.

METHODS

Mothers of normal newborns were randomized at 5 weeks infant age to a paper diary first (n = 34) or e-diary first (n = 35) group. With 3 days between, mothers completed 7-day recordings on both the paper Baby's Day Diary and an analogous personal digital assistant e-diary for infant (sleep, awake alert, feeding, fussing, crying, inconsolable crying) and caregiver (carrying/holding, moving) behaviors, and completed post diary ease-of-use ratings and poststudy preference ratings.

RESULTS

Mothers found e-diaries less bothersome but similarly disruptive and enjoyable to paper diaries. At study end, more found e-diaries easier to use, less bothersome and more efficient. E-diary behaviors were consistently more frequent, but rarely different in duration, then paper diary behaviors. Time-stamped e-diary entries (1) generally declined across weeks, (2) were higher if e-diaries were used first, and (3) settled at a modal 2 to 3 entries/day by the second week.

CONCLUSIONS

For behavioral recording of infant and caregiver behaviors, mothers generally expressed more approval for e-diaries than paper diaries, but neither was considered onerous. E-diaries consistently report more frequent but similar durations of behaviors. If recording when convenient, daily diary entries trend toward 2 to 3 entries a day. The e-diary results provide convergent evidence that paper diary recordings of common infant and caregiver behavior durations provide good estimates of durations, but that behavioral frequencies may be underestimated.

Electronic versus paper diaries: a pilot study of concordance and adherence in head and neck cancer patients receiving radiation therapy

Background

Interactive Voice Response Systems (IVRS) and other electronic data collection methods have begun to replace conventional paper diaries as a way to capture daily patient reports. However, these methods have not been compared in head and neck (H&N) cancer patients receiving radiation therapy.

Methods

15 subjects with H&N cancer were asked to complete daily IVRS calls and daily paper diaries during radiation therapy. We compared response consistency and comparative adherence across the two methods.

Results

86.1% (1920/2231) of participants' responses were consistent between IVRS and paper diaries. 79.5% of the expected number of paper diaries were completed, compared to 66.2% of IVRS phone calls.

Conclusions

In this pilot study of H&N cancer patients undergoing radiation therapy, concordance was high between responses recorded by paper diaries and IVRS. Although adherence appeared to be higher for the paper diaries, it is possible that they may not have been completed at the proper time.

Multilevel factor analysis and structural equation modeling of daily diary coping data: Modeling trait and state variation

The current study used multilevel modeling of daily diary data to model within-person (state) and between-person (trait) components of coping variables. This application included the introduction of multilevel factor analysis (MFA) and a comparison of the predictive ability of these trait/state factors. Daily diary data was collected on a large (n = 366) multiethnic sample over the course of five days. Intraclass correlation coefficient for the derived factors suggested approximately equal amounts of variability in coping usage at the state and trait levels. MFAs showed that Problem-Focused Coping and Social Support emerged as stable factors at both the within-person and between-person levels. Other factors (Minimization, Emotional Rumination, Avoidance, Distraction) were specific to the within-person or between-person levels, but not both. Multilevel structural equation modeling (MSEM) showed that the prediction of daily positive and negative affect differed as a function of outcome and level of coping factor. The Discussion section focuses primarily on a conceptual and methodological understanding of modeling state and trait coping using daily diary data with MFA and MSEM to examine covariation among coping variables and predicting outcomes of interest.

Feasibility of a daily electronic survey to study prevention behavior with HIV-infected individuals

The daily experiences of persons living with HIV (PLWH) are important but under-studied as predictors of HIV prevention behavior. Ecological momentary assessment (EMA) is an intensive within-subjects data collection method that can be used to examine daily experiences. To determine whether PLWH would participate in EMA, we conducted a feasibility study with 21 PLWH. The method was acceptable to men and women from diverse backgrounds, with 81% (17/21) completing 2 months of daily surveys, and 67% (14/21) completing 6 months. Measures were completed on 72% of study days. Only 6% of records had missing data. Daily survey completion decreased over time. Participants reported that EMA was easy and did not influence their behaviors. Results suggest EMA is feasible with PLWH.

Feasibility of using interactive voice response to monitor daily drinking, moods, and relationship processes on a daily basis in alcoholic couples

BACKGROUND

Daily process research on alcohol involvement has used paper-and-pencil and electronic data collection methods, but no studies have yet tested the feasibility of using Interactive Voice Response (IVR) technology to monitor drinking, affective, and social interactional processes among alcoholic (ALC) couples. This study tested the feasibility of using IVR with n = 54 ALC couples.

METHODS

Participants were n = 54 couples (probands who met criteria for a past 1-year alcohol use disorder and their partners) recruited from a substance abuse treatment center and the local community. Probands and their partners reported on their daily drinking, marital interactions, and moods once a day for 14 consecutive days using an IVR system. Probands and partners were on average 43.4 and 43.0 years old, respectively.

RESULTS

Participants completed a total of 1,418 out of a possible 1,512 diary days for an overall compliance rate of 93.8%. ALC probands completed an average of 13.3 (1.0) diary reports, and partners completed an average of 13.2 (1.0) diary reports. On average, daily IVR calls lasted 7.8 (3.0) minutes for ALC probands and 7.6 (3.0) minutes for partners. Compliance was significantly lower on weekend days (Fridays and Saturdays) compared to other weekdays for probands and spouses. Although today's intoxication predicted tomorrow's noncompliance for probands but not spouses, the strongest predictor of proband's compliance was their spouse's compliance. Daily anxiety and marital conflict were associated with daily IVR nonresponse, which triggered automated reminder calls.

CONCLUSIONS

Findings supported that IVR is a useful method for collecting daily drinking, mood, and relationship process data from alcoholic couples. Probands' compliance is strongly associated with their partners' compliance, and automated IVR calls may facilitate compliance on high anxiety, high conflict days.

Experience Sampling Methods: A Modern Idiographic Approach to Personality Research

Experience sampling methods are essential tools for building a modern idiographic approach to understanding personality. These methods yield multiple snapshots of people's experiences over time in daily life and allow researchers to identify patterns of behavior within a given individual, rather than strictly identify patterns of behavior across individuals, as with standard nomothetic approaches. In this article, we discuss the origin and evolution of idiographic methods in the field of personality and explain how experience sampling methods function as modern day idiographic methods in this field. We then review four primary ways in which experience sampling methods have been used to foster idiographic approaches in personality research. Specifically, we highlight approaches that examine individual differences in temporal and behavioral distributions, situation-behavior contingencies, daily processes, and the structure of daily experience. Following a brief methodology primer, we end by discussing future directions for idiographic experience sampling approaches in personality psychology and beyond.

Exploring the benefits of conscientiousness: an investigation of the role of daily stressors and health behaviors

BACKGROUND AND PURPOSE

This study investigated the impact of conscientiousness and its facets on health behaviors and daily hassles (stressors) and the moderating effects of conscientiousness on the hassles-health behavior relationship

METHODS

Four hundred and twenty-two employees completed daily diaries over 4 weeks. Day-to-day within-person effects of daily hassles on health behaviors were examined, together with the influence of conscientiousness.

RESULTS

Using hierarchical multivariate linear modeling, the results showed that conscientiousness was associated with lower consumption of high-fat snacks and more fruit and higher caffeine intake and smoking (in smokers) across the 28-day study period. Facets of conscientiousness were also found to moderate the effects of daily hassles on vegetable consumption, smoking, and likelihood of exercising each day. Participants with higher levels of order exercised more on days when they experienced daily hassles, whereas participants with lower levels of self-efficacy consumed less vegetables on stressful days. Among smokers, those with higher levels of self-discipline reported smoking more on days when they encountered hassles.

CONCLUSIONS

These findings indicate that conscientiousness and its facets may influence health status directly via changes in health behaviors and indirectly through influencing stress-health behavior relations.

Early follow-up data from seizure diaries can be used to predict subsequent seizures in same cohort by borrowing strength across participants

Accurate prediction of seizures in persons with epilepsy offers opportunities for both precautionary measures and preemptive treatment. Previously identified predictors of seizures include patient-reported seizure anticipation, as well as stress, anxiety, and decreased sleep. In this study, we developed three models using 30 days of nightly seizure diary data in a cohort of 71 individuals with a history of uncontrolled seizures to predict subsequent seizures in the same cohort over a 30-day follow-up period. The best model combined the individual's seizure history with that of the remainder of the cohort, resulting in 72% sensitivity for 80% specificity, and 0.83 area under the receiver operating characteristic curve. The possibility of clinically relevant prediction should be examined through electronic data capture and more specific and more frequent sampling, and with patient training to improve prediction.

Couples Coping with Stress

The primary objective of the study was to increase understanding of interpersonal dimensions of stress and coping within married couples. Our sample included 82 couples living in a stepfamily context. Data were collected using structured telephone interviews and twice-daily questionnaires for a period of 1 week. Using matched-pair hierarchical linear modeling analysis, the study examined how stress and coping processes unfold over the course of a given day and across days within couples. First, we investigated antecedents of empathic responding, a form of relationship-focused coping. Second, we examined the role of empathic responding in within-couple variations in marital tension across days. We found that when greater personal significance was attached to family stressors, husbands and wives tended to increase their use of empathic responding. Also considered were the contextual effects of marital adjustment on how family stressors are experienced and managed by couples. The results indicate a link between marital adjustment and the use of empathic responding for both husbands and wives within couples. As well, the study suggests that marital adjustment plays an important role in determining whether the negative effects of stress will persist across days. Higher use of empathic responding was found to be associated with lower levels of next-day marital tension. When relational outcomes are considered, empathic responding may represent an adaptive way of coping with everyday stress. Our findings indicate that examination of relationship-focused coping may add to the theoretical and explanatory power of current models of stress and coping.

Ecological momentary assessment

Assessment in clinical psychology typically relies on global retrospective self-reports collected at research or clinic visits, which are limited by recall bias and are not well suited to address how behavior changes over time and across contexts. Ecological momentary assessment (EMA) involves repeated sampling of subjects' current behaviors and experiences in real time, in subjects' natural environments. EMA aims to minimize recall bias, maximize ecological validity, and allow study of microprocesses that influence behavior in real-world contexts. EMA studies assess particular events in subjects' lives or assess subjects at periodic intervals, often by random time sampling, using technologies ranging from written diaries and telephones to electronic diaries and physiological sensors. We discuss the rationale for EMA, EMA designs, methodological and practical issues, and comparisons of EMA and recall data. EMA holds unique promise to advance the science and practice of clinical psychology by shedding light on the dynamics of behavior in real-world settings.

Daily process methodology for measuring earlier antidepressant response

OBJECTIVE

Rapid onset of therapeutic action for antidepressant medication represents a major area of unmet medical need, and any such effects have been difficult to detect using standard study designs and measurement strategies. We conducted a randomized, open-label study with blinded raters using daily process assessment vs. standard weekly assessment to answer the following study questions: 1) is it possible to detect an antidepressant response more rapidly with daily assessment than with standard assessment approaches? 2) what is the burden of daily assessment on participants relative to standard clinical assessments? and 3) does the process of completing daily assessments have any effect on clinic-based assessments such as the Hamilton Depression Rating Scale (HAM-D)?

METHOD

Seventy-eight outpatients with major depressive disorder who received open-label fluoxetine were randomized to standard weekly clinic assessment or standard weekly clinic assessment plus daily assessment, and were followed for 28 days. Data were collected between September, 2002 and August, 2003.

RESULTS

Daily assessment appeared to have no effect on 17-item HAM-D or MADRS scores obtained in the clinic. Survival analyses revealed that daily diaries detected therapeutic effects more quickly than did standard weekly clinic assessments, across most endpoints. Perceived burden of study participation was not significantly increased by daily diary completion, nor reflected in higher dropout rates.

CONCLUSION

Daily process assessment improves the ability to detect an early antidepressant response.

Construct validity of a multidimensional electronic pain diary for adolescents with arthritis

The aim of this study was to evaluate the construct validity and feasibility of a multidimensional electronic pain diary (e-Ouch(c)) in adolescents with juvenile idiopathic arthritis (JIA). Two descriptive studies with repeated measures were conducted between January and December 2005. Participants were drawn from a large metropolitan rheumatology clinic in a university affiliated pediatric tertiary care centre. In Study 1, 76 adolescents with active arthritis recorded their pain three times a day for 2weeks using the e-Ouch(c). In Study 2, 36 adolescents recorded their pain three times a day for 1week before and 2weeks after joint injections. Adolescents in both studies completed multiple measures to determine the construct validity and feasibility of the e-Ouch(c). Adolescents reported mild levels of pain intensity, unpleasantness, and interference as well as stiffness, and mild to moderate levels of fatigue. e-Ouch(c) average weekly pain unpleasantness and interference scores were higher in adolescents with higher pain intensity scores. Correlations between average weekly pain ratings on the e-Ouch(c) and scores from: (a) recalled least, average and worst weekly pain, (b) health-related quality of life and pain coping, and (c) disease activity were as predicted. Pain ratings were significantly lower following joint injections with effect sizes in the low to moderate and moderate to high ranges at the first and second week post-injection, respectively. These findings provide evidence of the construct validity and feasibility of the e-Ouch(c) electronic diary in adolescents with JIA. Use of real-time data capture approaches should be considered in future studies of chronic arthritis.

Health anxiety moderates the daytime cortisol slope

OBJECTIVES

Edwards et al. argue that a steeper daytime cortisol slope indicates increased symptom awareness [Edwards S, Hucklebridge F, Clow A, Evans P. Components of the diurnal cortisol cycle in relation to upper respiratory symptoms and perceived stress. Psychosom Med, 2003;65:320-7]. Theory suggests that health anxiety (HA) is associated with increased symptom awareness. Therefore, this study tests the hypothesis that higher levels of HA are associated with a steeper daytime cortisol slope and is the first to examine the daytime diurnal cortisol slope for HA.

METHODS

Forty-two healthy working adults completed measures of HA and neuroticism as well as indices to measure the severity and frequency of symptom reporting. Participants also provided eight consecutive days of salivary cortisol data. Two cortisol measures were taken each day -- once prior to lunch and once in the early evening -- the timing of these was synchronized to waking times. The data were analyzed using multilevel modeling.

RESULTS

The hypothesis was supported, with those scoring higher on HA showing a steeper daytime cortisol slope. There were no significant relationships between cortisol (average production and slope) and either neuroticism or symptom reporting (severity and frequency).

CONCLUSIONS

The results are interpreted as consistent with theories of HA that emphasis increased awareness of nonspecific symptoms.

One day at a time: The impact of daily satisfaction with spouse responses on pain, negative affect and catastrophizing among individuals with rheumatoid arthritis

The majority of research on pain catastrophizing has focused on its negative consequences for adjustment to chronic pain, with few investigations of factors that influence catastrophizing or its detrimental effects. Using a daily process methodology, the current study examined, first, the extent to which a supportive social environment plays a role in reduced catastrophizing, and second, the extent to which support might protect against the detrimental effects of catastrophizing on well-being. Sixty-nine married individuals with rheumatoid arthritis took part in an initial background interview, followed by twice daily telephone interviews (regarding pain intensity, negative affect, catastrophizing and satisfaction with spouse responses) for 1 week. Multi-level modeling indicated several pathways through which satisfaction with spouse responses disrupts the vicious cycle of pain, negative affect and catastrophizing. Consistent with past research, catastrophizing was associated with increases in pain and negative affect. However, when individuals reported increases in satisfaction with spouse responses they were less likely to experience increases in negative affect due to catastrophizing. Satisfaction with spouse responses also reduced the likelihood of feeling overwhelmed and helpless in dealing with daily pain. The relationship between pain and catastrophizing was attenuated in the context of increases in satisfaction with spouse responses. Negative affect was associated with increases in catastrophizing, but only when individuals reported decreases in satisfaction with spouse responses. Overall, findings were consistent with a model in which satisfaction with spouse responses serves as a coping resource, and suggests the importance of involving close others in treatments to reduce pain and catastrophizing.
