General Description

The data-bodily-distress-psyctr dataset is based on a network meta-analysis on cognitive behavioral interventions and acceptance- and mindfulness-based interventions for adults with bodily distress. The dataset contains study information and effect size data of randomized controlled trials that report the effect of cognitive behavioral as well as acceptance- and mindfulness-based interventions on somatic symptom severity, depressive symptoms, anxiety symptoms, health anxiety, and perceived health status. The dataset also contains information about negative effects and treatment satisfaction. This dataset includes psychotherapy versus control (psy vs ctr) comparisons. The date of the last search update is provided here. The results of the network meta-analysis can be found in this published article.

The dataset follows the Metapsy data standard. All included information has been independently extracted by two researchers. Risk of bias ratings were conducted using the Cochrane Collaboration Risk of Bias Tool 2 (RoB 2). Re-ratings using the Metapsy Risk of Bias tool are currently ongoing.

Variable Description

VariableDescription
author[author(s)] et al., [year]
condition_arm1Condition in the first trial arm. The condition name is standardized to ensure comparability across trials (e.g. cbt for all trial arms that employed cognitive-behavioral psychotherapy).
condition_arm2Condition in the second trial arm. The condition name is standardized to ensure comparability across trials (e.g. wlc for all trial arms that employed a waitlist control group).
multi_arm1In multiarm trials, this variable provides a specification of the type of treatment used in the first arm. This variable is set to NA (missing) when the study was not a multiarm trial. For example, if a multiarm trial employed two types of CBT interventions, face-to-face and Internet-based, this variable would be set to f2f and Internet, respectively.
multi_arm2In multiarm trials, this variable provides a specification of the type of treatment used in the second arm. This variable is set to NA (missing) when the study was not a multiarm trial. For example, if a multiarm trial employed two types of control groups, waitlist and placebo, this variable would be set to wl and plac, respectively. Typically, multiarm trials employ two or more active treatments (e.g. CBT and problem-solving therapy), which are compared to the same control group (e.g. a waitlist). This means that values in multi_arm2 do not differ (e.g. they are always wl for this specific multiarm trial); nevertheless, the variable should be specified in the dataset.
outcomeThis variable encodes the measured outcome: somatic symptoms (som), depression (depr), anxiety (anx), perceived health status (phs), health anxiety (ha)
outcome_typeThis variable encodes the type of outcome that builds the basis of the comparison, e.g. response, remission or deterioration. This is variable is particularly relevant for dichotomous effect size data, because it indicates what the event counts refer to. The msd factor level is typically used for outcomes expressed in means and standard deviations.
instrumentThis variable describes the instrument through which the relevant outcome was measured.
timeThe measurement point at which the outcome was obtained (e.g. post or follow-up).
time_weeksThe measurement point at which the outcome was obtained, in weeks after randomization (set to NA if this information was not available).
ratingThis variable encodes if the measured outcome was self-reported ("self-report") or clinician-rated ("clinician").
baseline_m_arm1Mean of the outcome in the first arm at baseline.
baseline_m_arm2Mean of the outcome in the second arm at baseline.
baseline_sd_arm1Standard deviation of the outcome in the first arm at baseline.
baseline_sd_arm2Standard deviation of the outcome in the second arm at baseline.
mean_arm1Mean of the outcome in the first arm at the measured time point.
mean_arm2Mean of the outcome in the second arm at the measured time point.
sd_arm2Standard deviation of the outcome in the second arm at the measured time point.
sd_arm1Standard deviation of the outcome in the first arm at the measured time point.
n_arm1Sample size in the first trial arm
n_arm2Sample size in the second trial arm.
