Abstract

As more cancer treatments take place in outpatient settings, family caregivers provide essential care and emotional support over long periods. Unaddressed patient and caregiver psychological distress can lead to worse outcomes, reflecting the challenges of managing complex care demands in the home setting. This systematic review and meta‐analysis examined how well nonpharmacologic interventions (NPIs) reduce distress, anxiety, and depression in adult patients with solid tumors and their family caregivers. The authors included 68 randomized controlled trials (RCTs) with a total of 11,987 participants. NPIs were characterized as psychoeducation, therapeutic counseling, skills training, or behavior modification. By using random‐effects models (Hedges g), they observed that NPIs significantly reduced patient distress at both 0.0–3.0 months (g = 0.13) and 3.1–6.0 months (g = 0.18), but NPIs did not significantly reduce caregiver distress. In the short term (0.0–3.0 months), NPIs also significantly reduced anxiety (g = 0.31 for patients; g = 0.15 for caregivers) and depression (g = 0.28 for patients; g = 0.25 for caregivers). Subgroup analyses examined the impact of patient and caregiver characteristics along with NPI type, delivery format, dose, and duration. NPIs delivered jointly to patients and caregivers yielded significant effects that were higher compared with NPIs delivered separately. NPIs can help manage distress in patients and reduce anxiety and depression in both patients and caregivers. However, the lack of long‐term follow‐up limits our understanding of their impact on patients and caregivers with prolonged or delayed psychological symptoms (PROSPERO registration number CRD42024536629).

TL;DR

This systematic review and meta-analysis of 68 RCTs with 11,987 participants found that nonpharmacologic interventions significantly reduced patient distress in the short and intermediate term and short-term anxiety/depression in patients and caregivers, but effects generally did not persist beyond 3 months except for patient distress and caregiver depression up to 3.1–6.0 months. Caregiver distress did not significantly improve at any time point.

Key findings

  • Among 68 RCTs and 11,987 participants, NPIs significantly reduced patient distress at 0.0–3.0 months (g = 0.13; 95% CI, 0.03–0.23; p = .008) and 3.1–6.0 months (g = 0.18; 95% CI, 0.02–0.34; p = .027), but not beyond 6.0 months (g = 0.05; 95% CI, −0.09 to 0.18; p = .520). Caregiver distress was not significantly reduced at 0.0–3.0 months (g = 0.05; p = .581), 3.1–6.0 months (g = 0.22; p = .198), or >6.0 months (g = 0.22; p = .140).
  • In the short term (0.0–3.0 months), NPIs significantly reduced patient anxiety (g = 0.31; 95% CI, 0.16–0.46; p = .000), caregiver anxiety (g = 0.15; 95% CI, 0.02–0.28; p = .023), patient depression (g = 0.28; 95% CI, 0.17–0.40; p = .000), and caregiver depression (g = 0.25; 95% CI, 0.11–0.38; p = .000).
  • Caregiver depression remained significant at 3.1–6.0 months (g = 0.22; 95% CI, 0.01–0.43; p = .037) but not beyond 6.0 months (g = 0.25; 95% CI, −0.04 to 0.54; p = .095); patient anxiety and depression were not significant after 3 months.
  • Subgroup analyses found therapeutic counseling was associated with significant reductions in patient and caregiver anxiety and depression; dyad-together delivery significantly reduced patient distress and anxiety/depression in both groups; mixed face-to-face/remote formats significantly reduced patient distress, anxiety, and depression; higher attrition was associated with smaller effects for patient and caregiver anxiety and caregiver depression.

Methods

  • Systematic review and meta-analysis conducted per PRISMA 2020, registered with PROSPERO (CRD42024536629); databases searched included Medline, Cochrane CENTRAL, APA PsycInfo, CINAHL, ClinicalTrials.gov, and WHO ICTRP through January 27, 2025 (CINAHL through December 11, 2023).
  • Included 68 RCTs (70 reports) of adult patients with solid tumors and their adult family caregivers; excluded children with cancer and patients with hematologic malignancies. NPIs were categorized as psychoeducation (k = 9), therapeutic counseling (k = 33), skills training (k = 20), or behavior modification (k = 6).
  • Outcomes were grouped at 0.0–3.0, 3.1–6.0, and >6.0 months; random-effects models used Hedges g; heterogeneity assessed with Cochran Q; subgroup and meta-regression analyses examined moderators; sensitivity used leave-one-study-out; publication bias assessed with Egger t-test; GRADE assessed certainty. The 68 RCTs included 5,795 patients and 6,192 caregivers; median NPI dose was 6.0 hours, 6.0 sessions, and 6.0 weeks.

Limitations

  • Stated in the paper: risk of bias was assessed only for primary outcomes of each RCT; 12 studies were excluded because of incomplete or incompatible data; excluded caregivers were younger but represented a smaller sample (1,443 vs. 6,192 included); certainty of evidence was moderate for short-term outcomes and low to very low for longer-term outcomes; generalizability was limited by concentration in high-income countries, predominantly female and Caucasian samples, and poor race/ethnicity reporting outside the United States; patients with hematologic malignancies and dyads in which both members were willing and able to participate were excluded; pharmacologic treatments were addressed in only two RCTs; bereavement-related outcomes were outside scope; and heterogeneity across studies limits precision of pooled estimates.
  • Evident from the text: long-term follow-up was limited, with most RCTs assessing outcomes within the first 3 months (n = 59) versus intermediate (n = 22) and long-term (n = 14) outcomes; the median contact time of approximately 6 hours may explain short-term benefits and limited durability; and 27 RCTs (39.7%) did not report disease stage, limiting interpretation by cancer stage.

  • The paper relies on this without support.

    The outcome measures for distress, anxiety, and depression across the included RCTs are sufficiently comparable to be pooled in meta-analysis.

    “Table 3 reports pooled effect sizes, 95% confidence intervals (CIs), heterogeneity across studies (Q statistic), and publication bias (Egger t‐test).”
  • The paper relies on this without support.

    The Egger t-test is a valid method for assessing publication bias in this meta-analysis.

    “The Egger t‐test detected no funnel plot asymmetry for all outcomes at 0.0–3.0 and 3.1–6.0 months (Table 3).”
  • The paper relies on this without support.

    The median contact time of approximately 6 hours is a meaningful measure of intervention dose.

    “The median contact time was approximately 6 hours, likely explaining the short‐term benefits and the limited durability.”

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Caregiver-distress short-term interval changes to 0.0-3.9 months

    Minor

    The caregiver-distress result in the prose uses 0.0-3.9 months, while the corresponding Table 3 row and Figure 3 caption specify 0.0-3.0 months.

  • Multicenter caregiver-depression result is called significant despite p = .052

    Minor

    The text says multicenter RCTs showed significant reductions in caregiver depression, but Table 4 gives that subgroup p = .052 and a confidence interval crossing zero. The row also carries a significance asterisk despite the table's definition of that symbol as p < .05.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-14.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-14.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
