What the Research Says About Social Habits

A 10-Minute VR Nature Video Won't Fix Your Loneliness — But a Phone Call with a Stranger Might Cut Your Depression Score by 1.7 Points

Here’s the number that should make you skeptical of the next wellness trend you see: zero. That’s the number of participants, control groups, or statistical results in the widely-cited editorial proposing a 7-day protocol of 360-degree VR nature videos and reflective writing to combat pandemic isolation. The paper, published in Cyberpsychology, Behavior, and Social Networking, is a theoretical proposal — not a study. Meanwhile, a pragmatic randomized controlled trial of 435 socially isolated older adults found that a structured telephone-based behavioural activation programme (up to eight weekly sessions) reduced depression scores by about 1.7 points on the PHQ-9 scale (0–27) at three months compared to usual care plus a wellbeing resource pack. That’s not a miracle cure. But it’s a real, measurable effect from an intervention you can actually do today without buying a headset.

What the research actually shows

The strongest evidence for improving mental health through social habits comes from structured, repeated, and often low-tech interventions — not passive consumption or one-off experiences. The BASIL+ trial (n=435, mean age 75.7, all with two or more chronic conditions and at least mild depression) tested behavioural activation delivered via telephone. The intervention group was offered up to eight weekly sessions (30–45 minutes each) focused on scheduling activities that provided achievement, pleasure, or social connection. At three months, the intervention group scored 1.7 points lower on the PHQ-9 than controls. That’s a small-to-moderate effect, but it’s clinically meaningful for people already in the mild-to-moderate range.

The OASIS trial (n=3,755 university students with insomnia) provides a different angle: improving sleep directly reduces social-cognitive symptoms. A 6-week digital CBT-I programme reduced paranoia (Cohen’s d = 0.19) and hallucinations (Cohen’s d = 0.24). The mediation analysis confirmed that sleep improvement caused the reduction in psychotic experiences — not the other way around. For your social habits, this means that if you’re sleeping poorly, your perception of social threats is likely distorted. Fix the sleep first, then worry about the social skills.

A meta-analysis of 66 RCTs (n=18,467) on app-based mental health interventions found small-to-moderate effect sizes for depression, anxiety, and stress compared to doing nothing. But critically, these apps did not outperform face-to-face therapy or computerized treatment when directly compared. The effect sizes were roughly equivalent to moving from moderate to mild symptom severity — not from severe to normal. Apps are a bridge, not a destination.

The meta-analysis of depression prevalence during COVID-19 (12 community studies, ~50,000–60,000 participants) found that roughly 1 in 4 people screened positive for depression during the early pandemic — about 7 times higher than the global baseline of 3.44%. This isn’t an intervention study, but it tells you something important: under major stress, your baseline mood will drop. Plan for it. Don’t wait until you feel bad to start a social routine.

The nuance most people miss

The most important nuance is that not all social contact is equal, and the quality of the interaction matters more than the quantity. The editorial on “Zoom fatigue” — while lacking original data — identifies a real mechanism: videoconferencing causes higher cognitive load because you’re processing non-verbal cues without normal body language, maintaining constant eye contact, and watching yourself on screen. The author suggests that audio-only breaks and reducing on-screen face size can mitigate exhaustion. If your social habit is a daily Zoom call, you might be making things worse, not better.

The L2 instruction meta-analysis (49 studies, ~2,300 learners) found that explicit teaching methods were roughly twice as effective as implicit methods for language learning. The implication for social habits: if you’re trying to learn a new social skill (e.g., how to make small talk, how to give a compliment), you need explicit instruction and practice — not just exposure. “Just put yourself out there” is implicit. “Here’s a script for three conversation starters, practice them with one person today” is explicit.

The exercise study (n=49 adolescent females with depression) found that an 8-week group jogging program (five 50-minute sessions per week at 60–70% max heart rate) significantly reduced depressive symptoms and stress hormones — but these effects reversed when participants stopped. Social habits are maintenance behaviours, not one-time fixes.

The BASIL+ trial also had a 96.1% White sample. We don’t know if these effects generalize across cultures or socioeconomic backgrounds. The app meta-analysis excluded people with severe mental illness. If you’re in that category, these findings may not apply to you.

Practical implications

• Schedule a structured, recurring social activity with a clear goal. The BASIL+ trial used up to eight weekly sessions of 30–45 minutes. That’s a minimum dose. Don’t just “try to be more social.” Pick a specific activity (e.g., a weekly phone call with a friend where you discuss one thing you accomplished and one thing you’re grateful for) and do it at the same time each week.

• Fix your sleep before you fix your social life. The OASIS trial showed that improving sleep reduces paranoia and hallucinations with effect sizes of d=0.19 and d=0.24. If you’re sleeping less than 6 hours or waking frequently, your social perception is likely distorted. Use a digital CBT-I programme (like Sleepio, which was used in the trial) for 6 weeks before investing energy in social skills training.

• Use audio-only calls for deep conversations. The Zoom fatigue editorial suggests that videoconferencing increases cognitive load due to constant eye contact and self-view. For emotionally demanding conversations, switch to audio-only. Save video for low-stakes check-ins.

Design your own experiment

What to test: Whether a weekly, structured, 30-minute phone call with a friend or family member reduces your depression or anxiety scores compared to your baseline.

How long to run it: 8 weeks minimum. The BASIL+ trial used up to 8 sessions, and the exercise study showed effects at 8 weeks. Shorter than that and you’re measuring novelty, not habit.

What to measure: Your PHQ-9 score (depression) and GAD-7 score (anxiety) once per week, at the same time of day. Both are free, validated, and take 2 minutes to complete. Track them in a spreadsheet. Also track your sleep quality (use a 1–10 scale each morning) and your social satisfaction (1–10 scale after each call).

What confound to watch for: The biggest confound is life events. If you start a new job, end a relationship, or experience a major stressor during the 8 weeks, your data will be noisy. Note these events in your log. Also watch for the “reverse causation” trap: if you feel better, you might call people more. The intervention is the scheduled call, not the spontaneous one. Stick to the schedule.

What a positive result looks like: A consistent decrease of at least 2 points on the PHQ-9 (the minimal clinically important difference) from your baseline average in weeks 1–2 to your average in weeks 7–8. A decrease of 1.7 points (the BASIL+ effect) is a realistic target. If you see no change, try switching to an in-person activity (e.g., a weekly walking meeting) or adding a sleep intervention first.
