Predictors of Dropout Among Psychosomatic Rehabilitation Patients During the COVID-19 Pandemic: Secondary Analysis of a Longitudinal Study of Digital Training

BACKGROUND

High dropout rates are a common problem reported in web-based studies. Understanding which risk factors interrelate with dropping out from the studies provides the option to prevent dropout by tailoring effective strategies.

OBJECTIVE

This study aims to contribute an understanding of the predictors of web-based study dropout among psychosomatic rehabilitation patients. We investigated whether sociodemographics, voluntary interventions, physical and mental health, digital use for health and rehabilitation, and COVID-19 pandemic-related variables determine study dropout.

METHODS

Patients (N=2155) recruited from 4 psychosomatic rehabilitation clinics in Germany filled in a web-based questionnaire at T1, which was before their rehabilitation stay. Approximately half of the patients (1082/2155, 50.21%) dropped out at T2, which was after the rehabilitation stay, before and during which 3 voluntary digital trainings were provided to them. According to the number of trainings that the patients participated in, they were categorized into a comparison group or 1 of 3 intervention groups. Chi-square tests were performed to examine the differences between dropout patients and retained patients in terms of sociodemographic variables and to compare the dropout rate differences between the comparison and intervention groups. Logistic regression analyses were used to assess what factors were related to study dropout.

RESULTS

The comparison group had the highest dropout rate of 68.4% (173/253) compared with the intervention groups' dropout rates of 47.98% (749/1561), 50% (96/192), and 42.9% (64/149). Patients with a diagnosis of combined anxiety and depressive disorder had the highest dropout rate of 64% (47/74). Younger patients (those aged <50 y) and patients who were less educated were more likely to drop out of the study. Patients who used health-related apps and the internet less were more likely to drop out of the study. Patients who remained in their jobs and patients who were infected by COVID-19 were more likely to drop out of the study.

CONCLUSIONS

This study investigated the predictors of dropout in web-based studies. Different factors such as patient sociodemographics, physical and mental health, digital use, COVID-19 pandemic correlates, and study design can correlate with the dropout rate. For web-based studies with a focus on mental health, it is suggested to consider these possible dropout predictors and take appropriate steps to help patients with a high risk of dropping out overcome difficulties in completing the study.

Longitudinal Evaluation of an Integrated Post-COVID-19/Long COVID Management Program Consisting of Digital Interventions and Personal Support: Randomized Controlled Trial

BACKGROUND

The postacute COVID-19 syndrome (PACS) can be addressed with multidisciplinary approaches, including professional support and digital interventions.

OBJECTIVE

This research aimed to test whether patients who received a health care facilitation program including medical internet support from human personal pilots and digital interventions (intervention group [IG] and active control group [ACG]) would experience fewer symptoms and have higher work ability and social participation than an untreated comparison group (CompG). The second objective was to compare the impact of a diagnostic assessment and digital interventions tailored to patients' personal capacity (IG) with that of only personal support and digital interventions targeting the main symptoms (ACG).

METHODS

In total, 1020 patients with PACS were recruited. Using a randomized controlled trial design between the IG and the ACG, as well as propensity score matching to include the CompG, analyses were run with logistic regression and hierarchical-linear models.

RESULTS

Symptoms decreased significantly in all groups over time (βT1-T2=0.13, t549=5.67, P<.001; βT2-T4=0.06, t549=2.83, P=.01), with a main effect of the group (β=-.15, t549=-2.65, P=.01) and a more pronounced effect in the IG and ACG compared to the CompG (between groups: βT1-T2=0.14, t549=4.31, P<.001; βT2-T4=0.14, t549=4.57, P<.001). Work ability and social participation were lower in the CompG, but there was no significant interaction effect. There were no group differences between the IG and the ACG.

CONCLUSIONS

Empowerment through personal pilots and digital interventions reduces symptoms but does not increase work ability and social participation. More longitudinal research is needed to evaluate the effects of a diagnostic assessment. Social support and digital interventions should be incorporated to facilitate health care interventions for PACS.

Patients' Post-/Long-COVID Symptoms, Vaccination and Functional Status-Findings from a State-Wide Online Screening Study

(1) Background: Better understanding of post-/long-COVID and limitations in daily life due to the symptoms as well as the preventive potential of vaccinations is required. It is unclear whether the number of doses and timepoint interrelate with the trajectory of post-/long-COVID. Accordingly, we examined how many patients positively screened with post-/long-COVID were vaccinated and whether the vaccination status and the timepoint of vaccination in relation to the acute infection were related to post-/long-COVID symptom severity and patients' functional status (i.e., perceived symptom severity, social participation, workability, and life satisfaction) over time. (2) Methods: 235 patients suffering from post-/long-COVID were recruited into an online survey in Bavaria, Germany, and assessed at baseline (T1), after approximately three weeks (T2), and approximately four weeks (T3). (3) Results: 3.5% were not vaccinated, 2.3% were vaccinated once, 20% twice, and 53.3% three times. Overall, 20.9% did not indicate their vaccination status. The timepoint of vaccination was related to symptom severity at T1, and symptoms decreased significantly over time. Being vaccinated more often was associated with lower life satisfaction and workability at T2. (4) Conclusions: This study provides evidence to get vaccinated against SARS-CoV-2, as it has shown that symptom severity was lower in those patients who were vaccinated prior to the infection compared to those getting infected prior to or at the same time of the vaccination. However, the finding that being vaccinated against SARS-CoV-2 more often correlated with lower life satisfaction and workability requires more attention. There is still an urgent necessity for appropriate treatment for overcoming long-/post-COVID symptoms efficiently. Vaccination can be part of prevention measures, and there is still a need for a communication strategy providing objective information about the usefulness and risks of vaccinations.

A Scoping Review of Digital Interventions that Treat Post-/Long-COVID

BACKGROUND

Patients with Post-/Long-COVID need support, and health care professionals require evidence-based patient care. Digital interventions can meet these requirements, especially if personal contact is limited.

OBJECTIVE

We reviewed evidence-based digital interventions, to help manage physical and mental health, for patients with Post-/Long-COVID.

METHODS

A scoping review was carried out; summarizing novel digital health interventions for treating Post-/Long-COVID patients. Using the PICO scheme, original studies were summarized in which patients with Post-/Long-COVID symptoms used digital interventions to help aid recovery.

RESULTS

From all scanned articles, k = 8 original studies matched the inclusion criteria. Three were "pre-test" studies. Three describe the implementation of a tele-rehabilitation program, one is a Post-/Long-COVID program, and one study describes the results of qualitative interviews with patients who used an online peer support group. Following the PICO scheme, we categorized previous studies: studies varied in terms of (P) participants, ranging from adults in different countries, such as former hospitalized patients with COVID-19, to disadvantaged communities in the UK, as well as health-care workers. In addition, the studies included patients who had previously been infected with COVID-19, who had ongoing symptoms, and some studies focused on specific symptoms, some post-COVID-19 or long-term. Other studies included patients in online peer support groups. The (I) interventions also varied. Most interventions used a combination of psychological and physical exercises, but they varied in duration, frequency, and social dimensions. The reviewed studies investigated physical and mental health (C) conditions of patients with Post-/Long-COVID. Most studies reported (O) outcomes/ improvements in physiological health perception, some physical conditions, fatigue, and some psychological aspects such as depression. However, some studies found no improvements in bowel/bladder problems, concentration, short-term memory, unpleasant dreams, physical ailments, perceived bodily pain, emotional ailments, and perceived mental health.

CONCLUSIONS

More systematic research with larger sample sizes is required to overcome sampling bias and include the health care professionals' perspective as well as help patients mobilize support by health care professionals and social network partners. The evidence so far suggests that patients should be provided with digital interventions to manage symptoms and reintegrate into everyday life, including work.

CLINICALTRIAL

Impact of the COVID-19 Pandemic on CSR Activities of Healthcare Providers

(1) Background: Corporate social responsibility (CSR) is important for every company that cares for sustainable structures. Healthcare providers especially have made social responsibility their goal. However, crises such as the COVID-19 pandemic impacted different activities within the healthcare sector including CSR and its monitoring. However, theory-driven CSR research within the healthcare sector is scarce and monitoring requires a structured understanding of the processes. Therefore, the objective of this study was to investigate the CSR practices and activities which healthcare providers have implemented in an exemplified country namely Germany and the effect of the pandemic in this process. (2) Methods: Participants were sampled based on their field of care (general, psychiatric, or rehabilitation), the type of organization (public, private, or non-profit), and group membership. A total of 18 healthcare providers were initially recruited, out of which nine participated in the interviews. They represent companies with yearly revenue of between EUR 110 million and EUR 6 billion, and have between 900 and 73,000 employees. (3) Results: CSR-related activities were postponed due to times of crisis. There was a necessity to rapidly digitalize processes. Frequent and precise communication turned out to be important for keeping employees' well-being, motivation, and satisfaction levels high. Environmental efforts were counteracted by new hygienic requirements and a shift in priorities. Many study participants expressed the hope that after the pandemic, newly established methods, processes, and structures (e.g., digital meetings, quicker and more inclusive communication) would be maintained and developed further. (4) Conclusions: The pandemic has been challenging and at the same time, these challenges also created opportunities to strike a new path using the learnings to overcome future health-related or economic crises.

Screening and assessment for post-acute COVID-19 syndrome (PACS), guidance by personal pilots and support with individual digital trainings within intersectoral care: a study protocol of a randomized controlled trial

Background

Because the clinical patterns and symptoms that persist after a COVID-19 infection are diverse, a diagnosis of post-acute COVID-19 syndrome (PACS) is difficult to implement. The current research project therefore aims to evaluate the feasibility and the practicability of a comprehensive, interdisciplinary, and cross-sectoral treatment program consisting of a low-threshold online screening and holistic assessment for PACS. Furthermore, it aims to evaluate digital interventions and the use of so-called personal guides that may help to facilitate the recovery of PACS.

Methods

This German study consists of a low-threshold online screening for PACS where positively screened participants will be supported throughout by personal pilots. The personal pilots are aimed at empowering patients and helping them to navigate through the study and different treatment options. Patients will then be randomly assigned either to an intervention group (IG) or an active control group (ACG). The IG will receive a comprehensive assessment of physiological and psychological functioning to inform future treatment. The ACG does not receive the assessment but both groups will receive a treatment consisting of an individual digital treatment program (digital intervention platform and an intervention via a chatbot). This digital intervention is based on the needs identified during the assessment for participants in the IG. Compared to that, the ACG will receive a more common digital treatment program aiming to reduce PACS symptoms. Importantly, a third comparison group (CompG) will be recruited that does not receive any treatment. A propensity score matching will take place, ensuring comparability between the participants. Primary endpoints of the study are symptom reduction and return to work. Secondary outcomes comprise, for example, social participation and activities in daily life. Furthermore, the feasibility and applicability of the online screening tool, the holistic assessment, digital trainings, and personal pilots will be evaluated.

Discussion

This is one of the first large-scale studies to improve the diagnosis and the care of patients with PACS by means of empowerment. It is to be evaluated whether the methods utilized can be used for the German and international population.

[Curriculum Hannover - Web-based vs. Analogue Psychotherapeutic aftercare after Psychosomatic Rehabilitation and vs. Care as Usual]

PURPOSE

In order to maintain the effect achieved in the psychosomatic rehabilitation measure, psychosomatic rehabilitation aftercare is indicated for most rehabilitation patients. Due to the low availability of aftercare therapists close to home, the use of digital offers is a possibility to enable access independent of location. The aim of the study was to evaluate the therapeutic effects of web-based aftercare in comparison to face-to-face (F2F) therapy (both on the conceptual basis of the Curriculum Hannover) in the equivalence study and to no standardized aftercare (care as usual, CAU) in the superiority study.

METHODS

300 rehabilitation patients with an indication for psychosomatic aftercare were assigned to the equivalence study if an aftercare service close to home was available and then randomized to F2F or online aftercare. Without a service close to home, the participants were assigned to the superiority study and randomized to online or CAU group. The outcomes (primary: psychological and somatoform complaints, secondary: subscales of the HEALTH-49, employment prognosis, ability to work) were assessed by online questionnaires at the end of rehabilitation, 9 or 12 and 15 or 18 months after rehabilitation and evaluated with multiple imputation and intention-to-treat-analyses. For the primary outcome, a sensitivity analysis was also carried out on the basis of the completed dataset.

RESULTS

After excluding non-adherent participants, n=142 participants were evaluated in the equivalence study and n=111 in the superiority study. In the equivalence study, no significant differences (d=0,28 and 0,10 with ITT-analyses; d=0,09 and 0,03 with completed dataset) were found between online and F2F follow-up with regard to short-term and long-term psychological and somatoform complaints. In the superiority study, long-term psychological and somatoform complaints decrease in the online group, while in the CAU group they first decreased at T2 (d=0,56) and increased again at T3 (d=0,72). The latter finding is confirmed with the analysis of the completed dataset (d=0,12), while an increase was seen in the online group at T3 (d=0,10).

CONCLUSION

According to the results of the present study, web-based psychosomatic aftercare seems to have a longer-term advantage for rehabilitants without access to previous aftercare. Compared to F2F implementation, it can be considered equivalent.

[Occupational and Health Strains of Pensioners with Reduced Earning Capacity Due to Mental or Physical Illnesses - Implications for the Health Care System]

OBJECTIVE

Demographic changes with an increasing number of people receiving pensions and a decreasing number of working people paying into the pension system represent major challenges for the German social security system. In particular, it is important to support people to continue working so that there is no (premature) reduction in their earning capacity and pensioners with reduced earning capacity (disability pensioners) should be helped to return to gainful employment. The aim of this study was to investigate the differing needs of two kinds of disability pensioners, namely those with mental illness and those who were physically ill.

METHODS

A total of 453 persons receiving disability pension because of temporararily reduced earning capacity were interviewed over the telephone. Differences in demographic variables, occupational characteristics before applying for disability pension, and general resources were examined in descriptive analyses and multivariate analyses of variance with post-hoc tests.

RESULTS

A third of the sample (33.1%) suffered from mental illness and the rest from somatic disorders. Those with mental illness reported higher perceived mental age, lower work-related self-efficacy, and lower quality of life concerning their mental health. Moreover, they reported higher levels of mental stressors at work.

CONCLUSION

Mentally ill disability pensioners differ considerably from those with somatic illnesses. Accordingly, to promote a return to work, interventions need to target different factors in these two groups.

Distress, loneliness, and mental health during the COVID-19 pandemic: Test of the extension of the Evolutionary Theory of Loneliness

COVID-19 restrictions such as lockdowns or quarantines may increase the risk for social isolation and perceived loneliness. The mechanisms can be modeled by Cacioppo's Evolutionary Theory of Loneliness (ETL), which predicts that a lack of perceived social connectedness may lead, in the long-term, to mental and physical health consequences. However, the association between COVID-19 pandemic distress, mental health, and loneliness is not sufficiently understood. The present longitudinal study examined the relationship between distress and depression, and the mediating effects of anxiety and loneliness in a German rehabilitation sample (N = 403) at two timepoints (≤6 weeks pre-rehabilitation; ≥12 weeks post-rehabilitation; mean time between T1 and T2 was  52 days). Change scores between T1 and T2 were examined for the variables COVID-19 Peritraumatic Distress Index (CPDI), anxiety, loneliness, and depression. The results of the serial mediation analysis indicated that anxiety and loneliness were able to explain the relationship between distress and depression with 42% of variance in depression accounted for. Findings extend research on the relationship between COVID-19 and mental health by considering anxiety and loneliness as sustaining factors of depressive symptoms, thus, successfully applying the ETL. Results stress the necessity to consider anxiety and loneliness in the treatment or prevention of depression.

[For Which Patients is Web-Based Psychotherapeutic Aftercare after Psychosomatic Rehabilitation Most Suitable?]

OBJECTIVE

In order to maintain the effects achieved during the psychosomatic rehabilitation, according aftercare is indicated for most rehabilitation patients. Due to the current low supply of aftercare psychotherapists (so-called aftercare therapists) licensed by the German Pension Insurance web-based aftercare provides an equivalent alternative to analogue (in person) offers. This study clarifies which characteristics indicate that web-based aftercare is particularly recommended and how web-based formats are evaluated by participants, especially with regard to the therapeutic relationship.

METHODS

142 psychosomatic rehabilitation patients were randomly assigned to analogue aftercare or web-based aftercare if a service close to their home was available (equivalence study design). Test variables were collected by questionnaires and analyzed stratified for age and gender.

RESULTS

For male participants, there are no significant differences between the two aftercare formats. Women appear to have lower long-term depression scores when participating in web-based aftercare. Participants till the age 50 benefit significantly more from web-based aftercare than rehabilitants above age 50, The quality of the therapeutic relationship is rated equally well in both aftercare formats.

DISCUSSION

Particularly in view of the increasing digitization of healthcare in times of the corona pandemic, web-based aftercare services offer the possibility of providing patients with aftercare independent of the availability of analogue-services and with the same benefits as analog therapies. Demographic factors such as age and sex must be taken into account when determining the indication.

CONCLUSION

Therapists should recommend web-based aftercare especially for younger patients and for women, while men and older patients can be recommended both services equally. Therapists who offer web-based aftercare should be trained in advance on technical and content-related aspects, as was done in the present work.

Adherence With Online Therapy vs Face-to-Face Therapy and With Online Therapy vs Care as Usual: Secondary Analysis of Two Randomized Controlled Trials

BACKGROUND

Adherence to internet-delivered interventions targeting mental health such as online psychotherapeutic aftercare is important for the intervention's impact. High dropout rates limit the impact and generalizability of findings. Baseline differences may be putting patients at risk for dropping out, making comparisons between online with face-to-face (F2F) therapy and care as usual (CAU) necessary to examine.

OBJECTIVE

This study investigated adherence to online, F2F, and CAU interventions as well as study dropout among these groups and the subjective evaluation of the therapeutic relationship. Sociodemographic, social-cognitive, and health-related variables were considered.

METHODS

In a randomized controlled trial, 6023 patients were recruited, and 300 completed the baseline measures (T1), 144 completed T2 (retention 44%-52%), and 95 completed T3 (retention 24%-36%). Sociodemographic variables (eg, age, gender, marital status, educational level), social-cognitive determinants (eg, self-efficacy, social support), health-related variables (eg, depressiveness), and expectation towards the treatment for patients assigned to online or F2F were measured at T1.

RESULTS

There were no significant differences between the groups regarding dropout rates (χ²₁=0.02-1.06, P≥.30). Regarding adherence to the treatment condition, the online group outperformed the F2F and CAU conditions (P≤.01), indicating that patients randomized into the F2F and CAU control groups were much more likely to show nonadherent behavior in comparison with the online therapy groups. Within study groups, gender differences were significant only in the CAU group at T2, with women being more likely to drop out. At T3, age and marital status were also only significant in the CAU group. Patients in the online therapy group were significantly more satisfied with their treatment than patients in the F2F group (P=.02; Eta²=.09). Relationship satisfaction and success satisfaction were equally high (P>.30; Eta²=.02). Combining all study groups, patients who reported lower depressiveness scores at T1 (T2: odds ratio [OR] 0.55, 95% CI 0.35-0.87; T3: OR 0.56, 95% CI 0.37-0.92) were more likely to be retained, and patients who had higher self-efficacy (T2: OR 0.57, 95% CI 0.37-0.89; T3: OR 0.52, 95% CI 0.32-0.85) were more likely to drop out at T2 and T3. Additionally, at T3, the lower social support that patients reported was related to a higher likelihood of remaining in the study (OR 0.68, 95% CI 0.48-0.96). Comparing the 3 intervention groups, positive expectation was significantly related with questionnaire completion at T2 and T3 after controlling for other variables (T2: OR 1.64, 95% CI 1.08-2.50; T3: OR 1.59, 95% CI 1.01-2.51).

CONCLUSIONS

While online interventions have many advantages over F2F variants such as saving time and effort to commute to F2F therapy, they also create difficulties for therapists and hinder their ability to adequately react to patients' challenges. Accordingly, patient characteristics that might put them at risk for dropping out or not adhering to the treatment plan should be considered in future research and practice. Online aftercare, as described in this research, should be provided more often to medical rehabilitation patients.

The Mediation Effect of Phobic Anxiety on the Treatment Outcome of Activity and Participation across Age: Comparison between Online and Face-to-Face Rehabilitation Aftercare of an RCT

The efficacy of internet and mobile-based interventions (IMIs) has been demonstrated with different mental health disorders, but little is known about the mediating effect of phobic anxiety on activity and participation and the differential effect of age. The current study tested a moderated mediation model with short-term change in phobic anxiety mediating between treatment (IMI vs. face-to-face, F2F) and long-term change in activity and participation, and age of patients moderating this mediation. Participants (N = 142) were recruited from psychosomatic rehabilitation clinics and randomized into the IMI psychosomatic aftercare or F2F psychosomatic aftercare. Moderated mediation analyses were conducted using R software. Results showed that the long-term treatment effects of activity and participation (βc = -0.18, p = 0.034; βc' = -0.13, p = 0.145) were improved through the successful decrease of phobic anxiety (βa = -0.18, p = 0.047; βb = 0.37, p = 0.010). Older patients benefited equally from both IMI and F2F interventions regarding short-term treatment change in phobic anxiety, while younger participants benefited more from IMI (βAge*Treatment = 0.20, p = 0.004). IMIs targeting mental disorders can improve activity and participation along with phobic anxiety, especially in younger individuals. The needs of older patients should be considered with the development and improvement of IMIs.

[Which Digital Services do Psychosomatic Rehabilitation Patients Use During the Corona Pandemic and do Interrelations with Anxiety and Depressive Symptoms Exist?]

OBJECTIVE

The COVID-19 pandemic requires numerous measures to protect against infection, such as contact reduction and adherence to hygiene and social distancing rules. The former leads to mental disorders (possibly requiring treatment) due to social isolation, the latter require adaptation in the implementation of medical therapies. With overall limited therapy capacities, the use of digital (health) applications can be of particular importance in the therapy of chronic and psychological diseases in particular. The present study investigates which health apps are being used by people with mental health problems.

METHODS

1,060 insured persons in preparation for psychosomatic rehabilitation measures were surveyed by means of an online questionnaire. Descriptive analyses, frequency analyses, and analyses of variance with post-hoc tests and correlation analyses were used for evaluation.

RESULTS

Participants used on average three apps; the most common topics were "nutrition" (n=313), "self-diagnosis" (n=244) and "relaxation" (n=234). Female participants were more likely to use apps than male participants, and younger participants were more likely to use apps than older participants. Symptoms of anxiety were correlated to the use of digital applications, especially concerning heart rate and blood pressure monitoring, while depressive symptoms were not associated with a more frequent use of apps.

DISCUSSION

Digital apps are being frequently used by people with mental health problems. Increasing acceptance of digital (health) apps has significant potential in the treatment of chronic mental illness in particular. The focus should be on individual applications with integration into the regular care process.

CONCLUSION

Increasing digitalization, also in the healthcare sector, can be used to ensure care, especially in times of contact restrictions and limited human resources.

Psychosomatic Rehabilitation Patients and the General Population During COVID-19: Online Cross-sectional and Longitudinal Study of Digital Trainings and Rehabilitation Effects

BACKGROUND

The COVID-19 pandemic has largely affected people's mental health and psychological well-being. Specifically, individuals with a pre-existing mental health disorder seem more impaired by lockdown measures posing as major stress factors. Medical rehabilitation treatment can help people cope with these stressors. The internet and digital apps provide a platform to contribute to regular treatment and to conduct research on this topic.

OBJECTIVE

Making use of internet-based assessments, this study investigated individuals from the general population and patients from medical, psychosomatic rehabilitation clinics. Levels of depression, anxiety, loneliness, and perceived stress during the COVID-19 pandemic, common COVID-19-related worries, and the intention to use digital apps were compared. Furthermore, we investigated whether participating in internet-delivered digital trainings prior to and during patients' rehabilitation stay, as well as the perceived usefulness of digital trainings, were associated with improved mental health after rehabilitation.

METHODS

A large-scale, online, cross-sectional study was conducted among a study sample taken from the general population (N=1812) in Germany from May 2020 to April 2021. Further, a longitudinal study was conducted making use of the internet among a second study sample of psychosomatic rehabilitation patients at two measurement time points-before (N=1719) and after (n=738) rehabilitation-between July 2020 and April 2021. Validated questionnaires and adapted items were used to assess mental health and COVID-19-related worries. Digital trainings were evaluated. Propensity score matching, multivariate analyses of covariance, an exploratory factor analysis, and hierarchical regression analyses were performed.

RESULTS

Patients from the psychosomatic rehabilitation clinics reported increased symptoms with regard to depression, anxiety, loneliness, and stress (F_4,2028=183.74, P<.001, η²_p=0.27) compared to the general population. Patients perceived greater satisfaction in communication with health care professionals (F_1,837=31.67, P<.001, η²_p=0.04), had lower financial worries (F_1,837=38.96, P<.001, η²_p=0.04), but had higher household-related worries (F_1,837=5.34, P=.02, η²_p=0.01) compared to the general population. Symptoms of depression, anxiety, loneliness, and perceived stress were lower postrehabilitation (F_1,712=23.21, P<.001, η²_p=0.04) than prior to rehabilitation. Psychosomatic patients reported a higher intention to use common apps and digital trainings (F_3,2021=51.41, P<.001, η²_p=0.07) than the general population. With regard to digital trainings offered prior to and during the rehabilitation stay, the perceived usefulness of digital trainings on rehabilitation goals was associated with decreased symptoms of depression (β=-.14, P<.001), anxiety (β=-.12, P<.001), loneliness (β=-.18, P<.001), and stress postrehabilitation (β=-.19, P<.001). Participation in digital group therapy for depression was associated with an overall change in depression (F_1,725=4.82, P=.03, η²_p=0.01) and anxiety (F_1,725=6.22, P=.01, η²_p=0.01) from pre- to postrehabilitation.

CONCLUSIONS

This study validated the increased mental health constraints of psychosomatic rehabilitation patients in comparison to the general population and the effects of rehabilitation treatment. Digital rehabilitation components are promising tools that could prepare patients for their rehabilitation stay, could integrate well with face-to-face therapy during rehabilitation treatment, and could support aftercare.

[Fear of Coronavirus, Intention to Follow the AHA Rules and Risk Perception Regarding Visits to the Doctor: Cross-sectional Study with Patients suffering from Pre-existing Mental Illness]

Ziel der Studie Die COVID-19-Pandemie erfordert zur Eindämmung Maßnahmen wie Kontaktbeschränkungen und Hygieneregeln und verursacht neben psychischen Problemen auch die Angst vor einer Ansteckung oder einem schweren Verlauf von COVID-19. Die vorliegende Arbeit untersucht den Zusammenhang zwischen der Angst vor einer Ansteckung und dem Einhalten von Hygieneregeln und der Inanspruchnahme medizinischer Versorgung.

Methodik Es wurden 1005 Patienten (20–79 Jahre, 626=62,4% weiblich) vor Antritt einer psychosomatischen Rehabilitationsmaßnahme mittels Online-Fragebogen befragt. Die Auswertung erfolgte deskriptiv, korrelativ und über Varianzanalysen.

Ergebnisse 68,6% hatten selten/manchmal und 17,9% hatten immer Angst vor einer Ansteckung mit dem Coronavirus oder vor einem schweren Verlauf der Krankheit. Wer oft/immer Angst hatte, beabsichtigte sich die Hände häufiger zu waschen (97,2%), als diejenigen, die nie Angst hatten. Unabhängig von einer Veränderung des körperlichen und psychischen Gesundheitszustandes waren die Patienten bereit, Hygienemaßnahmen einzuhalten. Jedoch hing mehr Angst vor Ansteckung mit mehr Risikowahrnehmung zusammen, medizinische Versorgung in Anspruch zu nehmen. Bedenken waren bei den Patienten am stäksten ausgeprägt, die einen verschlechterten Gesundheitszustand berichteten.

Schlussfolgerung Die Absicht des Befolgens der Hygieneregeln ist bei psychisch vorerkrankten Menschen abhängig von einer vorbestehenden Angst, sich selber oder andere mit dem Coronavirus anzustecken bzw. an einer schweren Verlaufsform zu erkranken. Insbesondere psychisch bzw. psychosomatisch vorerkrankte Menschen müssen adäquat über das Coronavirus und die notwendigen individuellen Schutzmaßnahmen informiert werden, um Ängste zu reduzieren und um die Bereitschaft zu steigern, medizinische Hilfe in Anspruch zu nehmen.

To What Extent is Internet Activity Predictive of Psychological Well-Being?

Background

Healthy internet activity (eg, making use of eHealth and online therapy) is positively associated with well-being. However, unhealthy internet activity (too much online time, problematic internet use/PIU, internet dependency/ID, etc.) is associated with reduced well-being, loneliness, and other related negative aspects. While most of the evidence is correlational, some research also shows that internet activity can be predictive for well-being.

Objective

The aim of this article is to elaborate on the question as to what extent internet activity is predictive of psychological well-being by means of (a) a scoping review and (b) theoretical understanding which model the interrelation of internet activity and psychological well-being.

Methodology

We searched different electronic databases such as Web of Science by using the search terms "Internet" OR "App" OR "digital" OR "online" OR "mobile application" AND "Use" OR "Activity" OR "Behavior" OR "Engagement" AND "Well-being" OR "Loneliness" for (a, the scoping review) or CCAM for (b, the theoretical understanding).

Results

The scoping review (a) summarizes recent findings: the extent to which internet activity is predictive for well-being depends on the internet activity itself: internet activity facilitating self-management is beneficial for well-being but too much internet activity, PIU and ID are detrimental to well-being. To understand (b) why, when and how internet activity is predictive for well-being, theoretical understanding and a model are required. While theories on either well-being or internet activity exist, not many theories take both aspects into account while also considering other behaviors. One such theory is the Compensatory Carry-Over Action Model (CCAM) which describes mechanisms on how internet use is related to other lifestyle behaviors and well-being, and that individuals are driven by the goal to adopt and maintain well-being - also called higher-level goals - in the CCAM. There are few studies testing the CCAM or selected aspects of it which include internet activity and well-being. Results demonstrate the potentials of such a multifactorial, sophisticated approach: it can help to improve health promotion in times of demographic change and in situations of lacking personnel resources in health care systems.

Conclusion and Recommendation

Suggestions for future research are to employ theoretical approaches like the CCAM and testing intervention effects, as well as supporting individuals in different settings. The main aim should be to perform healthy internet activities to support well-being, and to prevent unhealthy internet activity. Behavior management and learning should accordingly aim at preventing problematic internet use and internet dependency.

Cellular and humoral immune responses induced by intradermal or intramuscular vaccination with the major hepatitis B surface antigen

The vaccination route may influence the success of immunization against pathogens. The conventional intramuscular (i.m.) application of a vaccine containing the hepatitis B virus (HBV) surface antigen (HBsAg) led to protective anti-HBs antibody levels in the majority of vaccine recipients. In this study, we vaccinated healthy volunteers and a group of i.m. vaccine nonresponders via the intradermal (i.d.) route and analyzed the HBV-specific B-cell response as well as class-II- and class-I-restricted T-cell responses by (3)H-thymidine uptake, enzyme-linked immunosorbent assay (ELISA) and enzyme-linked immunospot assay (ELISPOT). The results were then compared with i.m. vaccinated controls. I.d. vaccinations were well tolerated and induced neutralizing anti-HBs antibodies in all naive vaccine recipients and, importantly, all but one former i.m. nonresponder developed protective anti-HBs serum antibody levels after 2 or 3 i.d. immunizations. On the cellular level, i.d. vaccine recipients showed significantly higher anti-HBs producing B-cell frequencies and more vigorous class-II-restricted T-helper (Th) cell responses than i.m. controls. However, although the HBsAg-specific T cells were characterized by their cytokine release as Th1-like cells in both groups, human leukocyte antigen (HLA)-A2+ individuals who received the soluble HBsAg via the i.d. route developed higher peptide-specific cytotoxic CD8+ T cell precursor (CTLp) frequencies. In conclusion, i.d. HBsAg vaccination is more effective even in former i.m. vaccine nonresponders with respect to antibody induction and specific B- and T-cell responses. The induction of virus-specific CTLp may provide the rationale to study the i.d. HBsAg vaccine in the treatment of chronic hepatitis B.

Granulocyte colony-stimulating factor (G-CSF) serum levels in surgical intensive care patients

The granulocyte colony-stimulating factor (G-CSF) regulates neutrophil differentiation and function. Serum levels of G-CSF increase during acute infectious processes. The levels of G-CSF were measured in 59 surgical intensive care unit (ICU) patients. In general, G-CSF was only elevated during the first 2 days after admission to the ICU. Higher G-CSF levels were more frequently observed in patients without infectious complications and in patients who survived. Later on, G-CSF levels were below 100 pg/ml in almost all patients studied. The highest G-CSF level (20,000 pg/ml) was observed in one patient with septic shock 36 h after leukopenia. The patient recovered from septic shock and multiple organ failure and was discharged. It is proposed that surgical ICU patients with low or undetectable G-CSF serum levels may benefit from exogenous G-CSF substitution protocols.

Cloning and recombinant expression of a barred sand bass (Paralabrax nebulifer) cDNA. The encoded protein displays structural homology and immunological crossreactivity to human complement/cofactor related plasma proteins

A new cofactor related cDNA in the bony fish Paralablax nebulifer, (barred sand bass) was isolated from a sand bass liver cDNA library. The clone (c71) is 1040 bp in size and the predicted translation product of 204 amino acids contains a hydrophobic signal peptide, which is followed by a region of three short consensus repeats (SCRs). The three SCRs display high homology to SCRs of the 110 kDa chain of the sand bass plasma cofactor protein, and to a lesser degree to human complement factor H related protein 3 (FHR-3) and to human factor H. Recombinant expression of the c71 cDNA in the baculovirus system shows a product of an apparent molecular mass of 27 kDa, which is secreted and glycosylated. It also contains a His-tag for purification purposes. Removal of the His-tag yields a 24 kDa protein, and deglycosylation further reduces the molecular mass to 21 kDa. This size is in agreement with the calculated molecular mass based on amino acid composition. The sand bass SBCFR-1 protein is immunologically related to the human complement proteins, factor H and factor H-related protein 3. The recombinantly expressed protein reacted with antisera against the human FHR-3 protein and SCRs 19-20 of human factor H. The presence of SCR-containing proteins in sand bass plasma and their structural and immunological homology to human FHR-3 and factor H suggests for a common function between these evolutionary related proteins.

Cloning and characterization of a cDNA representing a putative complement-regulatory plasma protein from barred sand bass (Parablax neblifer)

It has been demonstrated previously that plasma from a number of vertebrate species including the phylogenetically old barred sand bass possesses molecules that cleave the alpha'-chain of the activated third (C3b) and fourth (C4b) components of the human complement system. A specific protease and a cofactor protein were identified to be responsible for this cleavage. The cofactor activity in sand bass correlated with a 110 kDa polypeptide chain of a 360 kDa plasma protein. The evolutionary conservation was probed at the cDNA level and subsequently a cDNA clone of barred sand bass was isolated that represents a protein with structural similarity to mammalian complement-regulatory proteins. The cDNA (SB1) was identified by immunoscreening of a sand bass liver expression library using affinity-purified IgG antibodies raised against the isolated 110 kDa material. The cDNA is 3397 bp in size and the open reading frame represents a protein of 1053 amino acid residues with a hydrophobic signal peptide indicative of a secreted protein. The calculated mass of the mature protein (SBP1) is 115.2 kDa which is in good agreement with the molecular mass of 110 kDa determined for the sand bass serum protein. Similarly to mammalian complement-regulatory proteins, the protein deduced from the sand bass cDNA is organized into short consensus repeats (SCR). It consists of 17 SCRs, of which SCRs 2, 12 and 16 exhibit significant homology to SCRs 2, 15 and 19 of human factor H, and SCRs 11, 12 and 13 have homology to SCRs 1, 2 and 3 of human C4b-binding protein. For the first time a complete cDNA representing a putative complement-regulatory protein which is structurally related to mammalian complement proteins has been isolated from a bony fish.
