The relationship between social integration and depression in non-demented primary care patients aged 75 years and older

Linguistic Variables and Gender Differences Within a Messenger-Based Psychosocial Chat Counseling Service for Children and Adolescents: Cross-Sectional Study

BACKGROUND

Text messaging is widely used by young people for communicating and seeking mental health support through chat-based helplines. However, written communication lacks nonverbal cues, and language usage is an important source of information about a person's mental health state and is known to be a marker for psychopathology.

OBJECTIVE

The aim of the study was to investigate language usage, and its gender differences and associations with the presence of psychiatric symptoms within a chat counseling service for adolescents and young adults.

METHODS

For this study, the anonymized chat content of a German messenger-based psychosocial chat counseling service for children and adolescents ("krisenchat") between May 2020 and July 2021 was analyzed. In total, 661,131 messages from 6962 users were evaluated using Linguistic Inquiry and Word Count, considering the following linguistic variables: first-person singular and plural pronouns, negations, positive and negative emotion words, insight words, and causation words. Descriptive analyses were performed, and gender differences of those variables were evaluated. Finally, a binary logistic regression analysis examined the predictive value of linguistic variables on the presence of psychiatric symptoms.

RESULTS

Across all analyzed chats, first-person singular pronouns were used most frequently (965,542/8,328,309, 11.6%), followed by positive emotion words (408,087/8,328,309, 4.9%), insight words (341,460/8,328,309, 4.1%), negations (316,475/8,328,309, 3.8%), negative emotion words (266,505/8,328,309, 3.2%), causation words (241,520/8,328,309, 2.9%), and first-person plural pronouns (499,698/8,328,309, 0.6%). Female users and users identifying as diverse used significantly more first-person singular pronouns and insight words than male users (both P<.001). Negations were significantly more used by female users than male users or users identifying as diverse (P=.007). Similar findings were noted for negative emotion words (P=.01). The regression model of predicting psychiatric symptoms by linguistic variables was significant and indicated that increased use of first-person singular pronouns (odds ratio [OR] 1.05), negations (OR 1.11), and negative emotion words (OR 1.15) was positively associated with the presence of psychiatric symptoms, whereas increased use of first-person plural pronouns (OR 0.39) and causation words (OR 0.90) was negatively associated with the presence of psychiatric symptoms. Suicidality, self-harm, and depression showed the most significant correlations with linguistic variables.

CONCLUSIONS

This study highlights the importance of examining linguistic features in chat counseling contexts. By integrating psycholinguistic findings into counseling practice, counselors may better understand users' psychological processes and provide more targeted support. For instance, certain linguistic features, such as high use of first-person singular pronouns, negations, or negative emotion words, may indicate the presence of psychiatric symptoms, particularly among female users and users identifying as diverse. Further research is needed to provide an in-depth look into language processes within chat counseling services.

Emotion-dependent language featuring depression

BACKGROUND AND OBJECTIVES

Understanding language features of depression contributes to the detection of the disorder. Considering that depression is characterized by dysfunctions in emotion and individuals with depression often show emotion-dependent cognition, the present study investigated the speech features and word use of emotion-dependent narrations in patients with depression.

METHODS

Forty depression patients and forty controls were required to narrate self-relevant memories under five basic human emotions (i.e., sad, angry, fearful, neutral, and happy). Recorded speech and transcribed texts were analyzed.

RESULTS

Patients with depression, as compared to non-depressed individuals, talked slower and less. They also performed differently in using negative emotion, work, family, sex, biology, health, and assent words regardless of emotion manipulation. Moreover, the use of words such as first person singular pronoun, past tense, causation, achievement, family, death, psychology, impersonal pronoun, quantifier and preposition words displayed emotion-dependent differences between groups. With the involvement of emotion, linguistic indicators associated with depressive symptoms were identified and explained 71.6% variances of depression severity.

LIMITATIONS

Word use was analyzed based on the dictionary which does not cover all the words spoken in the memory task, resulting in text data loss. Besides, a relatively small number of depression patients were included in the present study and therefore the results need confirmation in future research using big emotion-dependent data of speech and texts.

CONCLUSIONS

Our findings suggest that consideration of different emotional contexts is an effective means to improve the accuracy of depression detection via the analysis of word use and speech features.

Social Support and Symptoms of Depression in Late Life: Bidirectional Associations over Time

Social support functions as an effective buffer against depression, especially among older adults with limited social networks. For the current study, we examined longitudinal bidirectional associations between social support and depression among those 75+ years of age. We recruited and followed a sample of Israeli adults 75+ years of age (N = 824; M = 80.84; range 75-96 years). Structured interviews were conducted in the homes of participants at three annual points of measurement. Participants reported depressive symptoms and emotional and instrumental support received from friends and family. We examined a cross-lagged, longitudinal structural equation model (SEM) in which social support and depressive symptoms predict each other over time, covarying for previously reported social support and depressive symptoms. We found that both depressive symptoms and social support are largely consistent in late life. Depressive symptoms and social support reported at baseline predict levels reported 1 and 2 years thereafter. Cross-over effects emerged over time. Depressive symptoms predicted lower social support in future, and social support at baseline predicted depressive symptoms 2 years later. These findings suggest that associations between depressive symptoms and social support are bidirectional in late life. Further research is needed to replicate findings in other cultures and over longer periods, ideally until end of life.

Social Network and Participation in Elderly Primary Care Patients in Germany and Associations with Depressive Symptoms-A Cross-Sectional Analysis from the AgeWell.de Study

This study aims to describe social network and social participation and to assess associations with depressive symptoms in older persons with increased risk for dementia in Germany. We conducted a cross-sectional observational study in primary care patients (aged 60−77) as part of a multicenter cluster-randomized controlled trial (AgeWell.de). We present descriptive and multivariate analyses for social networks (Lubben Social Network Scale and subscales) and social participation (item list of social activities) and analyze associations of these variables with depressive symptoms (Geriatric Depression Scale). Of 1030 included patients, 17.2% were at risk for social isolation (Lubben Social Network Scale < 12). Looking at the subscales, a reduced non-family network was found almost twice as often as a reduced family network. Patients with depressive symptoms had significantly smaller social networks than patients without depression (p < 0.001). They rather engaged in social activities of low involvement level or no weekly social activity at all (p < 0.001). The study shows associations of depressive symptoms with a decreased social network and less social participation in elderly participants. Sufficient non-family contacts and weekly social activities seem to play an important role in mental health and should be encouraged in elderly primary care patients.

Behavioral Activation and Depression Symptomatology: Longitudinal Assessment of Linguistic Indicators in Text-Based Therapy Sessions

BACKGROUND

Behavioral activation (BA) is rooted in the behavioral theory of depression, which states that increased exposure to meaningful, rewarding activities is a critical factor in the treatment of depression. Assessing constructs relevant to BA currently requires the administration of standardized instruments, such as the Behavioral Activation for Depression Scale (BADS), which places a burden on patients and providers, among other potential limitations. Previous work has shown that depressed and nondepressed individuals may use language differently and that automated tools can detect these differences. The increasing use of online, chat-based mental health counseling presents an unparalleled resource for automated longitudinal linguistic analysis of patients with depression, with the potential to illuminate the role of reward exposure in recovery.

OBJECTIVE

This work investigated how linguistic indicators of planning and participation in enjoyable activities identified in online, text-based counseling sessions relate to depression symptomatology over time.

METHODS

Using distributional semantics methods applied to a large corpus of text-based online therapy sessions, we devised a set of novel BA-related categories for the Linguistic Inquiry and Word Count (LIWC) software package. We then analyzed the language used by 10,000 patients in online therapy chat logs for indicators of activation and other depression-related markers using LIWC.

RESULTS

Despite their conceptual and operational differences, both previously established LIWC markers of depression and our novel linguistic indicators of activation were strongly associated with depression scores (Patient Health Questionnaire [PHQ]-9) and longitudinal patient trajectories. Emotional tone; pronoun rates; words related to sadness, health, and biology; and BA-related LIWC categories appear to be complementary, explaining more of the variance in the PHQ score together than they do independently.

CONCLUSIONS

This study enables further work in automated diagnosis and assessment of depression, the refinement of BA psychotherapeutic strategies, and the development of predictive models for decision support.

Depression Among Elderly Users of Open and Closed Care Facilities in a Rural Region of Greece: an Important Public Health Issue

Introduction:

It is estimated that 5.7% of the total Greek population suffers from depressive disorders. Elderly may be particularly prone to depression compared to younger people. In Greece, there is a paucity of literature regarding the correlation between the existence of chronic diseases, sociodemographic features, participation in open/ closed structures, and the presence of depression or depressive symptoms, among seniors. The purpose of this study was to explore potential correlations between the above- mentioned variables, as a whole.

Methods:

This was a cross- sectional, questionnaire survey of 200 elderly aged 65 or above and were members of 12 Open Care Centers for the Elderly (OCCE) or residents in 2 nursing homes located in the rural region of Epirus, in Greece. Data collection took place in the form of structured individual interviews. For the identification of independent factors associated with the existence of depressive symptoms, stepwise logistic regression analysis was performed.

Results:

A total of 81 (40.5%) seniors experienced depressive symptoms, though only 39 of them (19.5%) had been diagnosed for depression. Depression rates were higher for those with more chronic diseases (p=0.01) and at divorced, widowed and single seniors compared to married ones (50.5% vs. 28.1% respectively, p=0.002). The prevalence of depression was higher among the elderly who lived in nursing homes compared to the participants who were registered members of the OCCE (50% vs. 35.6% respectively, p=0.049), while elderly who often participated in the social activities of OCCE, had significantly lower rates of depressive symptoms compared to those who scarcely were involved in these activities (23% vs. 46.2% respectively, p=0.019). Participants who suffered from osteoporosis were more likely of displaying depressive symptoms compared to those who didn’t; OR (95% Confidence Interval) = 2.61 (1.28-5.33), p=0.009.

Conclusions:

The existence of an action plan that includes education and training of health professionals on mental health of the elderly and the satisfactory operation of public facilities to promote the wellbeing of seniors and offer more incentives for activity participation, may reduce depression rates and the under-diagnosis of the disease.

Loss experiences in old age and their impact on the social network and depression- results of the Leipzig Longitudinal Study of the Aged (LEILA 75+)

BACKGROUND

Loss experiences and bereavement are common among the oldest old. This study aims to investigate the effects of loss experiences and the social network type on depression in old age.

METHODS

As part of the Leipzig Longitudinal Study of the Aged (LEILA 75+), a representative population-based cohort study, 783 persons aged 75+ years were assessed via standardized interviews including the Practitioner Assessment of Network Type Instrument (PANT) and the Center for Epidemiologic Studies-Depression Scale (CES-D). Effects of loss experiences and network type on depression were analysed cross-sectionally (baseline survey) using logistic regressions. Effects over time were analysed longitudinally (follow-up1 and follow-up2) using hybrid techniques.

RESULTS

More than half of the elderly (57%) continuously lived in a restricted network. Only 12.1% lived in an integrated network. Although 30.9% had a change in their network, no significant association with loss experiences was found. Nevertheless, loss experiences (OR 7.56 (1.60-35.72)) and a restricted social network (OR 4.08 (1.52-10.95)) appeared to be the significant predictors of depression.

LIMITATIONS

Our study captures only a selected time window of the individual life and loss experience was only assessed at the time of the baseline survey.

CONCLUSION

Our findings revealed that elderly individuals, who experienced social loss or lived in restricted social networks, were more likely to develop depression compared to individuals who lived in integrated social networks or without loss experiences. The social integration of elderly individuals is an urgent issue that should be addressed in order to reduce depression in old age.

Review of treatment for late-life depression

Depressive disorder in those over the age of 60 has many clinical similarities to depression in younger adults, but biological changes related to ageing may necessitate a different approach to treatment. We present an evidence-based review of treatment for late-life depression, focusing on pharmacological approaches, including monotherapy, combination and augmentation strategies. Selective serotonin reuptake inhibitors such as sertraline and citalopram are well tolerated, have the advantage of a favourable side-effect profile, and are good options for first-line treatment. Second-line treatment options include combination therapy with a second antidepressant, or treatment augmentation with an antipsychotic or lithium. We also consider evidence for nonpharmacological treatment strategies, including psychological therapy and neurostimulation. Finally, we summarise evidence for treatment of depression in patients in dementia.

Positive Aging in Nursing Home Residents

Abstract. The main objective of nursing homes is to enable their residents a good life despite their existing physical, mental, and social health problems. In this cross-sectional study, we explored the mechanisms of positive aging in nursing-home residents from a salutogenic perspective. We interviewed 190 individuals (155 women) with a mean age of M = 84.3 years (SD = 7.60) and assessed selected resistance resources (subjective age, social network characteristics), the sense of coherence, and positive aging (psychological health and subjective well-being). The sense of coherence fully mediated perceived availability of social support and a younger age identification effects on positive aging. In line with salutogenic theory, it represents a superordinate concept which pools resource influences on positive aging.

The impact and measurement of social dysfunction in late-life depression: an evaluation of current methods with a focus on wearable technology

OBJECTIVE

Depression is known to negatively impact social functioning, with patients commonly reporting difficulties maintaining social relationships. Moreover, a large body of evidence suggests poor social functioning is not only present in depression but that social functioning is an important factor in illness course and outcome. In addition, good social relationships can play a protective role against the onset of depressive symptoms, particularly in late-life depression. However, the majority of research in this area has employed self-report measures of social function. This approach is problematic, as due to their reliance on memory, such measures are prone to error from the neurocognitive impairments of depression, as well as mood-congruent biases.

METHOD

Narrative review based on searches of the Web of Science and PubMed database(s) from the start of the databases, until the end of 2015.

RESULTS

The present review provides an overview of the literature on social functioning in (late-life) depression and discusses the potential for new technologies to improve the measurement of social function in depressed older adults. In particular, the use of wearable technology to collect direct, objective measures of social activity, such as physical activity and speech, is considered.

CONCLUSION

In order to develop a greater understanding of social functioning in late-life depression, future research should include the development and validation of more direct, objective measures in conjunction with subjective self-report measures. Copyright © 2016 John Wiley & Sons, Ltd.

The mediating role of depression in the association between disability and quality of life in Alzheimer's disease

BACKGROUND

An understanding of the determinants of quality of life in Alzheimer's disease (AD) is required in order to develop effective interventions to promote patients' well-being. Most studies have pointed out depression, functional ability and environmental factors. However, unmeasured confounders can jeopardize the interpretation of the results.

OBJECTIVES

To explore the mediating role of depression in the association between functional status and QoL, and establish a procedure to detect confounding variables.

METHODS

A sample of 192 AD patients and their respective caregivers were recruited from day centers and health care centers in the region of Murcia (Spain). The mediating effect was evaluated using causal mediation analysis. Covariates were introduced into the model in a stepwise fashion and sensitivity analyses were performed to assess the influence of potential confounders.

RESULTS

Self-rated depression acted as a partial mediator between functional status and quality of life. The mediating effect was positive and significant even after including both patient- and caregiver-related covariates. Only if confounders explained more than 80% of the residual variance in the mediator or in the outcome, the mediating effects would not be positive.

CONCLUSIONS

The effect of lack of autonomy on the QoL is mostly explained by the negative consequences on mood status. The sensitivity analysis confirms the robustness of this finding.

The role of spousal loss in the development of depressive symptoms in the elderly - implications for diagnostic systems

BACKGROUND

In the revised version of the Diagnostic and Statistical Manual of Mental Disorders (DSM) the Mood Disorder Workgroup for DSM-V the bereavement exclusion criterion for the diagnosis of major depression has been eliminated.

AIM

To investigate the impact of bereavement on the incidence of depression and depressive symptoms in the elderly.

METHOD

Participants over 75 years from the longitudinal German Study on Ageing, Cognition, and Dementia in Primary Care Patients (AgeCoDe) that were still married at baseline were investigated (n=1,193). Data from four follow-ups (time frame: 6 years) were investigated. The response rate at baseline was 50.3%. Three clinical endpoints were analyzed: depressive symptoms according to Geriatric Depression Scale (1) GDS≥6, (2) GDS≥10, and (3) Major Depression (MD). The effect of loss was investigated using random-effects regression models.

RESULTS

Experiencing a loss of spouse was predictive of a higher incidence in GDS≥6 (OR 4.52, 95% CI 2.6-7.9) and 10 (OR 5.59, 95% CI 1.8-17.0) even after adjusting for age, gender, impairment at baseline, and GDS score at baseline. Associations with MD were not significant (OR 1.77, 96% CI 0.9-3.5).

CONCLUSIONS

Older adults experiencing the loss of their spouse are more likely to display elevated levels of depressive symptoms, that may reach a concerning level of severity.

Prediction and structural equation model of sertraline treatment response in Japanese patients with major depressive disorder

OBJECTIVE

The aim of this study was to extract the factors possibly associated with sertraline treatment response and elucidate their interactions and extent of influence.

METHODS

Demographic state, stress state, personality, and eight genetic polymorphisms at baseline and clinical symptoms at baseline and 8 weeks were analyzed and examined by logistic regression and a structural equation model in sertraline treatment study of 96 Japanese patients with major depressive disorder.

RESULTS

Non-responders were associated with higher scores of harm avoidance in Temperament and Character Inventory, higher scores (≥24) of 17-item Hamilton Rating Scale for Depression at baseline, recurrence, and 12/12 genotype of the serotonin transporter variable number of tandem repeat polymorphism in intron 2 (5HTTSTin2). When we calculated the response index using four factors extracted, the mean response index value of non-responders was significantly higher than that of responders. The symptoms at baseline, personality, recurrence, and polymorphism of 5HTTSTin2 showed significantly direct and positive influences on the symptoms at 8 weeks in our final structural equation model with a good model fit.

CONCLUSION

Considering the combination of four factors extracted may be useful for predicting a worse response to sertraline treatment and selecting different treatment other than sertraline.

[Depression in old age: challenge for aging societies]

Depression in old age is common and has severe consequences. The paper reviews the most recent results of population-based and primary care-based studies reporting the prevalence, course and risk factors for depression in old age. Consequences of late life depression for the individual and for the society in terms of costs of illness are outlined. Studies of health service utilization and costs showed homogeneously that healthcare costs for depressive elderly individuals are one third higher compared to non-depressive individuals even though most do not receive depression-specific treatment. Late life depression is underrecognized and undertreated and data from Germany are rare. Improvement strategies, such as collaborative care models are discussed; however, adaptation and implementation to the German context are still pending. Future demographic changes will facilitate mental health service research into late life depression.
