HTAThe clinical effectiveness and costeffectiveness of low-intensity psychological interventions for the secondary prevention of relapse after depression: a systematic review NIHR Health Technology Assessment programmeThe Health Technology Assessment (HTA) programme, part of the National Institute for Health Research (NIHR), was set up in 1993. It produces high-quality research information on the effectiveness, costs and broader impact of health technologies for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined as all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care. The research findings from the HTA programme directly influence decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC). HTA findings also help to improve the quality of clinical practice in the NHS indirectly in that they form a key component ...

A systematic review of psychotherapeutic interventions for women with metastatic breast cancer: Context matters

“…These Web‐based and self‐care strategies form part of an emerging modality for receiving psychological interventions, termed “low‐intensity.” The primary purpose of low‐intensity interventions is to increase access to evidence‐based psychological therapies, using the minimum level of intervention necessary to create maximum gain and delivering content in a variety of flexible forms, including email, smart devices, telephone, print‐based resources, and internet . While definitions vary, the key attributes of low‐intensity interventions are that they are more accessible, use fewer formal health care professionals' resources compared with conventional therapies, and may use nonspecialist practitioners to deliver the programs . In contrast, group and individual psychotherapeutic interventions are high intensity, defined as therapist‐administered programs, delivered in‐person by health professionals with specialist training, and can be of either brief (less than 6 hours) or extensive duration .…”

What does it mean to have enough evidence?

“…For example, a recent review examined the clinical effectiveness and cost-effectiveness of psychological interventions in preventing relapse after depression. 19 This review, however, highlights one of the difficulties with this approach. The report is more than 100 pages long, with superb detailing of the search strategies, included and excluded studies and data extraction methods.…”

“…Unfortunately, however, no studies met the criteria for the clinical effectiveness component of the search, and the conclusion of the review was that there was inadequate evidence to determine whether the interventions of interest are clinically effect ive. 19 Even the best and most systematic reviews are limited by the availability of primary literature on the question of interest. Considering the effort and investment involved in some of the larger reviews, it is easy to wonder whether a preliminary screen could determine whether the primary evidence is extensive enough to predict the probability of a clinically relevant conclusion.…”

Web-Based Interventions for Depression in Individuals with Diabetes: Review and Discussion (Preprint)

“…Because psychological intervention studies are very often clinically and methodologically diverse [29], we hope that our review will be helpful for all researchers and clinicians willing to design web-based interventions for depression in individuals with diabetes in the future.…”
