Synchronous Web-Based Psychotherapy for Mental Disorders From a Health Quality Perspective: Scoping Review

BACKGROUND

The COVID-19 pandemic necessitated rapid changes to health care delivery, including a shift from in-person to digitally delivered psychotherapy. While these changes helped ensure timely psychotherapy provision, many concerns exist, including clinical, cultural, practical, privacy, and security issues.

OBJECTIVE

This scoping review systematically mapped existing peer-reviewed research on synchronous, therapist-delivered web-based psychotherapy for individuals with a diagnosed mental illness. Data were analyzed through the lens of the Alberta Quality Matrix for Health (AQMH) to assess to what degree this literature addresses key indicators of health care quality. This analysis aided in the identification and organization of knowledge gaps with regard to web-based psychotherapies, highlighting potential disparities between previously prioritized dimensions of care and those requiring further attention.

METHODS

This review adhered to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines. We included peer-reviewed primary research studies in the English language investigating synchronous, therapist-delivered remote psychotherapy delivered to adults (aged 18 years and older) with a Diagnostic and Statistical Manual of Mental Disorders or International Statistical Classification of Diseases diagnosed mental illness. All other citations were excluded. Relevant studies were identified through MEDLINE, APA PsycINFO, Embase (OVID), Web of Science: Core Collection (Clarivate), Cochrane Library (Wiley), and Scopus (Elsevier) databases. Databases were searched on March 18, 2021. For every publication that was taken into consideration, the data were charted independently by 2 reviewers, and in the event of a discrepancy, the principal investigator validated the choice of either extractor. Results were thematically described according to the 6 AQMH dimensions: acceptability, accessibility, appropriateness, effectiveness, efficiency, and safety.

RESULTS

From 13,209 publications, 48 articles were included, largely from North American studies. Most studies measured treatment effectiveness (n=48, 100%) and acceptability (n=29, 60%) health quality dimensions. Over 80% (40/48) of studies investigated either a cognitive or exposure intervention for either posttraumatic stress disorder or a mood or anxiety disorder, generally indicating comparable results to in-person therapy. Safety (n=5, 10%) was measured in fewer studies, while treatment accessibility, appropriateness, and efficiency were not explicitly measured in any study, although these dimensions were mentioned as a future direction, hypothesis, or potential outcome.

CONCLUSIONS

In relation to web-based therapist-delivered psychotherapies for those with a diagnosed mental illness, important aspects of health care quality (accessibility, appropriateness, efficiency, and safety) have received little scientific examination, underscoring a need to address these gaps. There are also significant issues related to the generalizability of this literature, including the underrepresentation of many geographic regions, cultures, populations, clinical contexts, and psychotherapy modalities. Qualitative research in underrepresented populations and settings may uncover important patient and contextual factors important for the future implementation of quality web-based psychotherapy.

Cultural accommodation of internet-based interventions for substance use and related disorders: a proposed comprehensive framework based on a pilot study and a literature review

Despite the low utilization rates of substance use and related disorders services, and the ability of internet-based interventions for substance use and related disorders (IBIS) to address challenges related to service engagement, limited attention has been placed on the processes for the accommodation of these interventions to diverse cultural settings. This study aimed to develop a framework for the cultural accommodation of IBIS across populations based on a pilot study and a literature review. A pilot study of cultural accommodation of an existing internet intervention for alcohol use was carried out in Israel, which involved focus groups and daily online surveys of prospective consumers (N = 24) as well as interviews with experts (N = 7) in the substance abuse treatment field. Thematic analysis revealed a range of themes that relate to the general Israeli culture and the specific Israeli drinking subculture, identified as needing to be addressed in the process of intervention accommodation. A comprehensive framework for cultural accommodation of IBIS is suggested, consisting of five stages: Technical and cultural feasibility; Engagement of target group; Identification of accommodation variables, Accommodation, and evaluation of the accommodated intervention. In addition, the framework consists of four dimensions of accommodation: Barriers and facilitators; Audio-visual materials and language; Mechanisms of change; Intersectional factors. We suggest that the proposed framework may serve as a guide for the cultural accommodation of existing internet-based interventions for substance use and related disorders across a range of cultural and geographical settings, thus augmenting the ecological validity of internet-based interventions for substance use and related disorders, expanding cross-cultural intervention research, and reducing health disparities worldwide.

It turned into something else: patients' long-term experiences of transitions to or from telepsychotherapy during the COVID-19 pandemic

Introduction

The shift from in-person therapy to telepsychotherapy during the COVID-19 pandemic was unprepared for, sudden, and inevitable. This study explored patients' long-term experiences of transitions to telepsychotherapy and back to the office.

Methods

Data were collected approximately two years after the declaration of COVID-19 as a pandemic. Eleven patients were interviewed (nine women and two men, aged 28 to 56, six in psychodynamic psychotherapy, five in CBT). Treatments switched between in-person and video/telephone sessions. Interview transcripts were analyzed applying the qualitative methodology of inductive thematic analysis.

Results

(1) The patients experienced the process in telepsychotherapy as impeded. Interventions were difficult to understand and lost impact. Routines surrounding the therapy sessions were lost. Conversations were less serious and lost direction. (2) Understanding was made more difficult when the nuances of non-verbal communication were lost. (3) The emotional relationship was altered. Remote therapy was perceived as something different from regular therapy, and once back in the therapy room, the patients felt that therapy started anew. The emotional presence was experienced as weakened, but some of the patients found expressing their feelings easier in the absence of bodily co-presence. According to the patients, in-person presence contributed to their security and trust, whereas they felt that the therapists were different when working remotely, behaving in a more easygoing and familiar way, as well as more solution-focused, supportive and unprofessional, less understanding and less therapeutic. Despite this, (4) telepsychotherapy also gave the patients an opportunity to take therapy with them into their everyday lives.

Discussion

The results suggest that in the long run, remote psychotherapy was seen as a good enough alternative when needed. The present study indicates that format alternations have an impact on which interventions can be implemented, which can have important implications for psychotherapy training and supervision in an era when telepsychotherapy is becoming increasingly common.

Remote Psychotherapy during the COVID-19 Pandemic: A Mixed-Methods Study on the Changes Experienced by Austrian Psychotherapists

The outbreak of the COVID-19 pandemic and associated measures to contain the SARS-CoV-2 coronavirus required a change in treatment format from face-to-face to remote psychotherapy. This study investigated the changes experienced by Austrian therapists when switching to psychotherapy at a distance. A total of 217 therapists participated in an online survey on changes experienced when switching settings. The survey was open from 26 June until 3 September 2020. Several open questions were evaluated using qualitative content analysis. The results show that the setting at a distance was appreciated by the therapists as a possibility to continue therapy even during an exceptional situation. Moreover, remote therapy offered the respondents more flexibility in terms of space and time. Nevertheless, the therapists also reported challenges of remote therapy, such as limited sensory perceptions, technical problems and signs of fatigue. They also described differences in terms of the therapeutic interventions used. There was a great deal of ambivalence in the data regarding the intensity of sessions and the establishment and/or maintenance of a psychotherapeutic relationship. Overall, the study shows that remote psychotherapy seems to have been well accepted by Austrian psychotherapists in many settings and can offer benefits. Clinical studies are also necessary to investigate in which contexts and for which patient groups the remote setting is suitable and where it is potentially contraindicated.

How the COVID-19 Pandemic Affects the Provision of Psychotherapy: Results from Three Online Surveys on Austrian Psychotherapists

This study aimed to assess patient numbers and the format in which psychotherapy was delivered by Austrian psychotherapists during different time points of the COVID-19 pandemic and to explore psychotherapists` experiences on pandemic-associated changes in their psychotherapeutic work as well as their wishes for support in their professional activities. Three cross-sectional online surveys were conducted between March 2020 and May 2022. The total number of participating psychotherapists was n = 1547 in 2020, n = 238 in 2021, and n = 510 in 2022. The number of patients treated was highest in 2022 and lowest at the beginning of the pandemic (p < 0.001). During the lockdown in 2020, only 25.0% of patients were treated in personal contact. This proportion increased in the following years, reaching 86.9% in 2022 (p < 0.001). After a substantial increase in the proportion of patients treated via the telephone and internet during the first lockdown, both proportions decreased during the pandemics' second and third year (p < 0.001). However, a larger proportion of patients were treated via the internet in 2022 compared to pre-pandemic times (p < 0.001). Psychotherapists reported that the pandemic affected mainly the setting in which psychotherapy was provided (29.6%), the working conditions and workload (27.1%), as well as the demand for psychotherapy (26.9%). About one-third of psychotherapists expressed support wishes for their psychotherapeutic work. Results suggest that the pandemic went along with a partial shift in the provision of psychotherapy towards psychotherapy via the internet but not the telephone. The increase in patient numbers and psychotherapists` reports of increased workload suggest a rise in the demand for mental health care during and in the aftermath of the pandemic.

Psychodynamic Therapist's Subjective Experiences With Remote Psychotherapy During the COVID-19-Pandemic-A Qualitative Study With Therapists Practicing Guided Affective Imagery, Hypnosis and Autogenous Relaxation

The COVID-19-pandemic brought massive changes in the provision of psychotherapy. To contain the pandemic, many therapists switched from face-to-face sessions in personal contact to remote settings. This study focused on psychodynamic therapists practicing Guided Affective Imagery, Hypnosis and Autogenous Relaxation and their subjective experiences with psychotherapy via telephone and videoconferencing during the first COVID-19 related lockdown period in March 2020 in Austria. An online survey completed by 161 therapists produced both quantitative and qualitative data with the latter being subject to a qualitative content analysis. Our research suggests that telephone and videoconferencing are considered valuable treatment formats to deliver psychodynamic psychotherapy. However, therapists' experiences with remote psychotherapy are multifaceted and ambiguous. In particular, the findings raise questions concerning the maintenance of the therapeutic alliance, the development of the analytic process, the sensitivity to unconscious communication, and the indication for certain types of patients that still need further investigation. Our research indicates that the long-standing reticence toward remote treatments offers among psychodynamic therapists is becoming more differentiated and partially dissolves as therapists gain experiences in their use. Attitudes are becoming more open. At the same time, the way is being prepared to take a closer look at the specific processes and dynamics of remote psychotherapy and to examine them critically in future studies.

Remote Psychotherapy During the COVID-19 Pandemic. Experiences With the Transition and the Therapeutic Relationship. A Longitudinal Mixed-Methods Study

Aims: Research conducted prior to the onset of the COVID-19 pandemic indicates that remote psychotherapy is as effective as in-person treatment. At that time, it usually was the therapist's individual choice to work remotely, whereas the pandemic pushed psychotherapists, including previous skeptics, to incorporate remote work methods into their routine due to limited face-to-face contact. There is little knowledge of the way therapists experienced this sudden and forced transition to remote psychotherapy as the only treatment option. The present study aims to assess psychotherapists' experience and proficiency delivering remote psychotherapy as well as to investigate perceived changes in the psychotherapeutic relationship. Methods: An online survey was administered to psychotherapists of the Austrian Association for Group Therapy and Group Dynamics (ÖAGG). Three test periods (t) were set (t1: April, 2020 with N = 175; t2: May-June, 2020 with N = 177; t3: November-December, 2020 with N = 113). Research was conducted longitudinally using a mixed-methods research design. Results: While psychotherapists' levels of experience with telephone-based psychotherapy remained similar across all test periods, they became slightly more experienced using video therapy over the test period observed. However, they continued to feel less experienced compared to the use of telephone-based psychotherapy. The therapeutic relationship appeared to improve over the course of the first two test periods, while the third period showed a slight decline. No general deterioration of the psychotherapeutic relationship was found in the timespan studied. Conclusion: Despite many challenges and concerns, psychotherapists seem to adapt and enhance their skills in remote psychotherapy over time. The present paper confirms and enhances previous findings in the field due to its longitudinal approach. Remote psychotherapy can be a credible and trustworthy alternative to in-person treatment to be adopted and implemented on principle by a majority of psychotherapists regardless of their orientation. Furthermore, it sheds light on chances, problems und general observations regarding the comprehensive provision of remote psychotherapy in a pandemic situation.

How Does It Feel to Be Online? Psychotherapists' Self-Perceptions in Telepsychotherapy Sessions During the COVID-19 Pandemic in Italy

Aims: The COVID-19 pandemic and consequent extreme restrictions imposed by governments across the world forced psychotherapists to abruptly change their working modality. The first aim of the current study was to assess psychotherapists’ self-perceptions (i.e., affective and cognitive perceptions about their self and their self in relation to clients) when providing telepsychotherapy during the first peak of the COVID-19 pandemic in Italy. The second aim was to explore the associations between psychotherapists’ self-perceptions, characteristics, and clinical practices.

Method: An online survey was administered to 281 Italian licensed psychotherapists (M_age=45.15; SD=10.2; 83.6% female) between April 5 and May 10, 2020. The survey comprised ad-hoc questions that were designed to collect sociodemographic details and information related to working practices. Moreover, a semantic differential (SD) scale was developed to assess psychotherapists’ self-perceptions, and a factor analysis was performed from the SD items.

Results: The SD scale showed an overall trend of positive psychotherapist self-perception during telepsychotherapy, despite reports of greater fatigue and directive and talkative behavior during sessions. Four SD factors accounted for 45% of the variance: “Affective Availability,” “Attitude Predisposition,” “Well-being,” and “Interventionism.” Scores on the first three factors were indicative of psychotherapists’ Positive vs. Negative self-perception. A comparison of the Positive and Negative attitudinal profiles using the chi-squared test with Yates’s correction and a Monte Carlo simulation found that psychotherapists with a Positive profile reported greater satisfaction with the telematic modality and were more likely to perceive that their clients were able to maintain privacy during sessions.

Conclusion: The results suggest that Italian psychotherapists have been able to promptly adapt to the imposed telematic modality during the COVID-19 pandemic. However, they may have attempted to compensate for their physical distance from clients by intervening more during sessions. These findings may support psychotherapists who are currently practicing and inform future practitioners who are considering the use of telematic treatment as a routine component of psychotherapeutic care.

Therapeutic Alliance in COVID-19 Era Remote Psychotherapy Delivered to Physically Ill Patients With Disturbed Body Image

The COVID-19 pandemic outbreak has led to a general reorganization of health services and an increase in outpatient telemedicine in mental healthcare for physically ill people. Current literature highlights facilitators and obstacles concerning the use of new technologies in psychotherapy, an underrated topic of research in the context of supportive expressive psychotherapy. More insight is needed to explore the characteristics of video in therapeutic alliance for treatment of specific mental disorders experienced in psychosomatics, particularly with people suffering from a disturbed body- and self-image. Using two clinical vignettes, it is the authors' intention to enrich the critical debate on current knowledge in psychosomatic remote psychotherapy, with special focus on mentalization deficits and their impact on therapeutic alliance in the consultation-liaison psychiatry setting. In particular, we will question the interpersonal processes at stake related to mirroring and the disruption caused by the use of videoconference applications. We will also reflect upon the relationship between the therapeutic alliance and the medical team, and that between patient and psychotherapist. The aim is to improve psychotherapeutic alliance maintained during the pandemic for specific mental disorders and to inform about possible clinical factors that could be the subject of future empirical studies or professional guidelines.

Comparing Chinese and US practitioners' attitudes towards teletherapy during the COVID-19 pandemic

INTRODUCTION

The China American Psychoanalytic Alliance (CAPA) has been offering psychoanalytic psychotherapy training and treatment to Chinese mental health professionals entirely over the Internet since 2006. When the COVID-19 pandemic began, most practitioners worldwide had to turn to teletherapy. US psychoanalytic practitioners were more negative towards teletherapy than those from other theoretical orientations. We predicted that CAPA practitioners as compared to US psychoanalytic practitioners would be more prepared for teletherapy services during the pandemic, since they their training and treatment had been on-line.

METHOD

We compared survey results from 164 CAPA practitioners with 165 US psychoanalytic practitioners (matched for age) who had recently psychoanalytically treated a patient on-line. CAPA participants were recruited from CAPA email lists and the US sample were recruited from the Society for Psychoanalysis and Psychoanalytic Psychology of the American Psychological Association, the American Psychoanalytic Association and International Psychotherapy Institute.

RESULTS

CAPA practitioners as compared to US psychoanalytic practitioners had more positive opinions about teletherapy before the pandemic; had more positive opinions about teletherapy during the pandemic; and had more positive opinions about the effectiveness of teletherapy in working with transference, relational issues and resistance. The CAPA practitioners were more prepared to do psychoanalytic psychotherapy during the pandemic than the US psychoanalytic practitioners.

DISCUSSION

Xiubing Wang discusses these findings in terms of her own experience as a CAPA graduate and treater before, during and after the COVID-19 pandemic in China.

Experiences of Psychotherapists With Remote Psychotherapy During the COVID-19 Pandemic: Cross-sectional Web-Based Survey Study

BACKGROUND

The current situation around the COVID-19 pandemic and the measures necessary to fight it are creating challenges for psychotherapists, who usually treat patients face-to-face with personal contact. The pandemic is accelerating the use of remote psychotherapy (ie, psychotherapy provided via telephone or the internet). However, some psychotherapists have expressed reservations regarding remote psychotherapy. As psychotherapists are the individuals who determine the frequency of use of remote psychotherapy, the potential of enabling mental health care during the COVID-19 pandemic in line with the protective measures to fight COVID-19 can be realized only if psychotherapists are willing to use remote psychotherapy.

OBJECTIVE

This study aimed to investigate the experiences of psychotherapists with remote psychotherapy in the first weeks of the COVID-19 lockdown in Austria (between March 24 and April 1, 2020).

METHODS

Austrian psychotherapists were invited to take part in a web-based survey. The therapeutic orientations of the psychotherapists (behavioral, humanistic, psychodynamic, or systemic), their rating of the comparability of remote psychotherapy (web- or telephone-based) with face-to-face psychotherapy involving personal contact, and potential discrepancies between their actual experiences and previous expectations with remote psychotherapy were assessed. Data from 1162 psychotherapists practicing before and during the COVID-19 lockdown were analyzed.

RESULTS

Psychotherapy conducted via telephone or the internet was reported to not be totally comparable to psychotherapy with personal contact (P<.001). Psychodynamic (P=.001) and humanistic (P=.005) therapists reported a higher comparability of telephone-based psychotherapy to in-person psychotherapy than behavioral therapists. Experiences with remote therapy (both web- and telephone-based) were more positive than previously expected (P<.001). Psychodynamic therapists reported more positive experiences with telephone-based psychotherapy than expected compared to behavioral (P=.03) and systemic (P=.002) therapists. In general, web-based psychotherapy was rated more positively (regarding comparability to psychotherapy with personal contact and experiences vs expectations) than telephone-based psychotherapy (P<.001); however, psychodynamic therapists reported their previous expectations to be equal to their actual experiences for both telephone- and web-based psychotherapy.

CONCLUSIONS

Psychotherapists found their experiences with remote psychotherapy (ie, web- or telephone-based psychotherapy) to be better than expected but found that this mode was not totally comparable to face-to-face psychotherapy with personal contact. Especially, behavioral therapists were found to rate telephone-based psychotherapy less favorably than therapists with other theoretical backgrounds.

Psychotherapy by Telephone or Internet in Austria and Germany Which CBT Psychotherapists Rate It more Comparable to Face-to-Face Psychotherapy in Personal Contact and Have more Positive Actual Experiences Compared to Previous Expectations?

Objectives: COVID-19 has led to changes in the provision in mental health services. The current study investigated influencing factors on: (i) the comparability of psychotherapy via internet/telephone with psychotherapy in face-to-face contact as well as (ii) the actual experience with psychotherapy via internet/telephone compared to respective prior expectations in CBT therapists. Methods: A quantitative cross-sectional study was conducted in the form of an online survey. The research samples, registered cognitive-behavioral therapy (CBT) psychotherapists in Austria and Germany, were contacted by e-mail. Results: One hundred and ninety CBT therapists were analyzed in this study. The total number of patients treated via telephone/internet is a decisive factor for the subjective evaluation of the comparability of psychotherapy via telephone/internet and psychotherapy in personal contact. This factor also influences the extent (positive/negative) of the assessment of the actual experience with psychotherapy via internet/telephone compared to previous expectations. Neither age nor gender were associated with comparability of psychotherapy via internet/telephone with psychotherapy in face-to-face contact or the actual experience with psychotherapy via internet/telephone compared to respective prior expectations. Conclusions: Implications of the results are that attitudes towards remote psychotherapy might be increased in CBT therapists when they treat more patients remotely and experiences with remote psychotherapies should be included in psychotherapy training.

Psychotherapy During COVID-19: How the Clinical Practice of Italian Psychotherapists Changed During the Pandemic

Aims: Italy was one of the first countries to be significantly affected by the coronavirus disease 2019 (COVID-19) pandemic, determining a unique scenario for Italian psychotherapists to consider changing the modality in which they deliver treatment. The present study aimed at studying which factors related to psychotherapists and their clinical practice had a major role in predicting two main outcomes: (1) the rate of interrupted treatments during lockdown and (2) psychotherapists' satisfaction with the telepsychotherapy modality. Methods: An online survey was administered to licensed psychotherapists (n = 306), who worked mainly as private practitioners, between April 5 and May 10, 2020 (i.e., the peak of the pandemic in Italy). Results: Psychotherapists reported that 42.1% (SD = 28.9) of their treatments had been interrupted, suggesting that Italy faced an important undersupply of psychotherapy during the lockdown. Using the Akaike information criterion (AIC) model selection, we identified three predictors of the rate of interrupted treatments: (1) psychotherapists' lack of experience with telepsychotherapy prior to the lockdown, (2) their theoretical orientation (with cognitive behavioral psychotherapists reporting a higher rate of interrupted treatments), and (3) patients' lack of privacy at home, as reported to the psychotherapists. Furthermore, we found four predictors of psychotherapists' satisfaction with the telepsychotherapy modality: (1) the rate of interrupted treatments, (2) psychotherapists' previous experience with telepsychotherapy, (3) their beliefs about the compatibility of telepsychotherapy with their theoretical orientation, and (4) their use of a video-conferencing modality, rather than telephone. Conclusion: The following recommendations can help policy makers, professional associations, and practitioners in promoting the continuity of psychotherapy treatments during the COVID-19 outbreak and in future emergencies: (i) disseminating training programs for practitioners on telepsychotherapy, (ii) supporting patients to pragmatically access a private space at home, (iii) encouraging practitioners to use video-conferencing (instead of telephone) to deliver remote therapy, and (iv) increasing the acceptance of telepsychotherapy among both clinicians and the general public.

Provision of Psychotherapy during the COVID-19 Pandemic among Czech, German and Slovak Psychotherapists

Psychotherapists around the world are facing an unprecedented situation with the outbreak of the novel coronavirus disease (COVID-19). To combat the rapid spread of the virus, direct contact with others has to be avoided when possible. Therefore, remote psychotherapy provides a valuable option to continue mental health care during the COVID-19 pandemic. The present study investigated the fear of psychotherapists to become infected with COVID-19 during psychotherapy in personal contact and assessed how the provision of psychotherapy changed due to the COVID-19 situation and whether there were differences with regard to country and gender. Psychotherapists from three European countries: Czech Republic (CZ, n = 112), Germany (DE, n = 130) and Slovakia (SK, n = 96), with on average 77.8% female participants, completed an online survey. Participants rated the fear of COVID-19 infection during face-to-face psychotherapy and reported the number of patients treated on average per week (in personal contact, via telephone, via internet) during the COVID-19 situation as well as (retrospectively) in the months before. Fear of COVID-19 infection was highest in SK and lowest in DE (p < 0.001) and was higher in female compared to male psychotherapists (p = 0.021). In all countries, the number of patients treated on average per week in personal contact decreased (p < 0.001) and remote psychotherapies increased (p < 0.001), with more patients being treated via internet than via telephone during the COVID-19 situation (p < 0.001). Furthermore, female psychotherapists treated less patients in personal contact (p = 0.036), while they treated more patients via telephone than their male colleagues (p = 0.015). Overall, the total number of patients treated did not differ during COVID-19 from the months before (p = 0.133) and psychotherapy in personal contact remained the most common treatment modality. Results imply that the supply of mental health care could be maintained during COVID-19 and that changes in the provision of psychotherapy vary among countries and gender.

Application of Synchronous Text-Based Dialogue Systems in Mental Health Interventions: Systematic Review

Background

Synchronous written conversations (or “chats”) are becoming increasingly popular as Web-based mental health interventions. Therefore, it is of utmost importance to evaluate and summarize the quality of these interventions.

Objective

The aim of this study was to review the current evidence for the feasibility and effectiveness of online one-on-one mental health interventions that use text-based synchronous chat.

Methods

A systematic search was conducted of the databases relevant to this area of research (Medical Literature Analysis and Retrieval System Online [MEDLINE], PsycINFO, Central, Scopus, EMBASE, Web of Science, IEEE, and ACM). There were no specific selection criteria relating to the participant group. Studies were included if they reported interventions with individual text-based synchronous conversations (ie, chat or text messaging) and a psychological outcome measure.

Results

A total of 24 articles were included in this review. Interventions included a wide range of mental health targets (eg, anxiety, distress, depression, eating disorders, and addiction) and intervention design. Overall, compared with the waitlist (WL) condition, studies showed significant and sustained improvements in mental health outcomes following synchronous text-based intervention, and post treatment improvement equivalent but not superior to treatment as usual (TAU) (eg, face-to-face and telephone counseling).

Conclusions

Feasibility studies indicate substantial innovation in this area of mental health intervention with studies utilizing trained volunteers and chatbot technologies to deliver interventions. While studies of efficacy show positive post-intervention gains, further research is needed to determine whether time requirements for this mode of intervention are feasible in clinical practice.
