name: globem-user-analysis description: > Comprehensive individual-user analysis on the GLOBEM dataset — a longitudinal passive-sensing + mental-health study of college students. Use this skill whenever a task involves analyzing a specific participant (e.g. "Analyze user INS-W_002") from the GLOBEM dataset, exploring behavioral patterns from smartphone sensors, correlating behavioral signals with mental health outcomes, or producing a comprehensive user profile from multimodal sensing data.

Recommended Execution Plan

Execute in this sequence (~14–18 execute_code calls total). Each call is dedicated — avoid combining multiple modalities into one call, as this degrades insight depth:

1. list_files → verify all files present
2. get_field_description on 2–3 sensor files (activity, sleep, location) to discover extra columns
3. Activity analysis (steps, bouts, weekday/weekend, T1/T2/T3, active/sedentary ratio)
4. Sleep analysis (duration, efficiency, timing, weekday/weekend, T1/T2/T3)
5. Communication analysis (counts, duration, proactivity ratio, call timing window, count/duration dissociation, T1/T2/T3)
6. Location analysis (distance, home time, entropy, circadian, flight duration, top locations, T1/T2/T3)
7. Phone usage analysis (unlock count, duration, session stats, home/study split, count/duration dissociation, T1/T2/T3)
8. Connectivity analysis (scan count, unique devices, scan efficiency, T1/T2/T3)
9. Mental health — weekly surveys (dep_weekly, ema, dep_endterm with T1/T2/T3 for feel_depressed, feel_anxious, subscales)
10. Mental health — pre/post surveys and personality (all scale changes with ↑↓ arrows)
11. Phase 4a — EMA ↔ behavioral correlations (all 6 pairs with r, p, n)
12. Phase 4b — Cross-behavioral correlations (all 6 pairs) + peak EMA event analysis (top 3 days)
13. Phase 4c — High vs. low EMA day comparisons + depression-flagged week comparisons
14. Consolidated temporal trends table (all key metrics: T1/T2/T3, early/late, % change, trajectory label)
15. Data quality summary + weekday/weekend verification for all modalities
16. Final synthesis (user profile with paradox identification)

Steps 11–14 are the most analytically rich and must all be completed.

Analysis Pipeline

Phase 1 — Orientation (1–2 calls)

# 1. list_files to confirm available files
# 2. get_field_description on 2-3 sensor files to learn extra column names
# Do NOT call get_field_description for dep_weekly, ema, pre, post, dep_endterm, platform

Phase 2 — Per-modality stats (one call per modality)

Filter all sensor DFs by pid == '<user_id>'. Always convert date to datetime first:

user_df['date'] = pd.to_datetime(user_df['date'])

CRITICAL — T1/T2/T3 and Early/Late date boundaries:

Always compute d_min/d_max from the full user dataframe including NaN rows. Never filter to valid rows first, or the date boundaries shift and all T1/T2/T3 values become wrong.

# CORRECT: use all 92 rows to anchor the date range
d_min, d_max = user_df['date'].min(), user_df['date'].max()
span = (d_max - d_min) / 3
t1 = user_df[user_df['date'] < d_min + span]          # NaN rows included; pandas .mean() skips them
t2 = user_df[(user_df['date'] >= d_min + span) & (user_df['date'] < d_min + 2*span)]
t3 = user_df[user_df['date'] >= d_min + 2*span]

mid = d_min + (d_max - d_min) / 2
early = user_df[user_df['date'] < mid]
late  = user_df[user_df['date'] >= mid]

# Report T1/T2/T3 and early/late means (pandas skips NaN by default)
t1_mean = t1[col].mean()
early_mean = early[col].mean()
late_mean  = late[col].mean()
pct_change = (late_mean - early_mean) / abs(early_mean) * 100  # early→late %

After computing T1/T2/T3, label the trajectory pattern:

• progressive increase: T1 < T2 < T3 (monotonic)
• progressive decline: T1 > T2 > T3 (monotonic)
• inverted-U: T2 > T1 and T2 > T3
• U-shaped: T2 < T1 and T2 < T3
• mixed/stable: no clear pattern

Verify sign consistency: The sign of the early→late % change must be consistent with the trajectory label (decline → negative %; increase → positive %). If they disagree, recheck the computation.

For each modality compute:

• Mean ± std, min/max over valid (non-NaN) rows
• Count of valid days (report as n/92)
• Weekday vs. weekend difference (df['date'].dt.dayofweek → 0–4 weekday, 5–6 weekend)
• T1/T2/T3 and early/late for all key metrics

Activity — Primary: intraday_rapids_sumsteps, intraday_rapids_countepisodesedentarybout, intraday_rapids_countepisodeactivebout. Compute and trend:

• Active/sedentary bout ratio and intraday_rapids_avgdurationsedentarybout (avg sedentary bout duration)
• T1/T2/T3 and early/late for: steps, active/sedentary ratio, avg sedentary bout duration, active bout count, sedentary bout count
• Weekday vs. weekend for steps (weekday steps often higher due to campus routine)

Sleep — summary_rapids_avgdurationasleepmain (minutes), summary_rapids_avgefficiencymain (already 0–100, never multiply by 100), summary_rapids_avgdurationtofallasleepmain, summary_rapids_firstbedtimemain, summary_rapids_lastwaketimemain. Convert bedtime/wake minutes-since-midnight to HH:MM. Compute and trend:

• T1/T2/T3 and early/late for: duration, efficiency, bedtime, wake time, time-to-fall-asleep
• Weekday vs. weekend for sleep duration and timing

Communication — Primary: rapids_outgoing_count, rapids_incoming_count, rapids_missed_count, rapids_outgoing_meanduration, rapids_incoming_meanduration, rapids_outgoing_distinctcontacts. Compute and trend:

• Outgoing/incoming ratio (>1 = proactive)
• Count/duration dissociation: explicitly note when count and duration trend in opposite directions
• Call timing window: rapids_outgoing_timefirstcall and rapids_outgoing_timelastcall (minutes from midnight → HH:MM); report shift between early and late periods
• T1/T2/T3 and early/late for: outgoing count, incoming count, missed count, outgoing/incoming ratio, distinct contacts, mean outgoing duration, call timing window
• Weekday vs. weekend for outgoing call count

Location — Primary: barnett_disttravelled, barnett_rog, barnett_hometime (minutes/day), barnett_circdnrtn (0–1), barnett_siglocsvisited, barnett_siglocentropy (nats), barnett_avgflightdur ± barnett_stdflightdur (seconds), doryab_avgspeed (km/hr), doryab_numberlocationtransitions, doryab_timeattop1location / doryab_timeattop2location / doryab_timeattop3location (minutes). Filter GPS outliers: drop values > median × 10 for barnett_disttravelled and barnett_rog before averaging. Compute and trend:

• T1/T2/T3 and early/late for: distance, radius of gyration, home time, circadian routine, location entropy, location transitions, significant places, avg flight duration, std flight duration, avg speed, top-1/top-2/top-3 location time
• Weekday vs. weekend for home time and distance
• Note: for students with remote/online classes, weekday home time can be GREATER than weekend home time — report both values and direction without assuming a fixed pattern

Phone Usage — Primary: rapids_countepisodeunlock, rapids_sumdurationunlock (minutes), rapids_avgdurationunlock, rapids_stddurationunlock, rapids_firstuseafter00unlock (minutes → HH:MM), rapids_sumdurationunlock_locmap_home, rapids_countepisodeunlock_locmap_home, rapids_countepisodeunlock_locmap_study. Compute and trend:

• Home-use fraction, count/duration dissociation if present (unlock count vs. avg session duration trending opposite directions)
• T1/T2/T3 and early/late for: unlock count, total duration, avg session duration, session std, first-use time, home unlocks, study unlocks
• Weekday vs. weekend for unlock count

Connectivity — rapids_countscans, rapids_uniquedevices. Scan efficiency = countscans / uniquedevices. Compute and trend:

• T1/T2/T3 and early/late for: scan count, unique devices, scan efficiency
• Weekday vs. weekend for scan count

Phase 3 — Mental health profile (2 calls)

Call 1 — Weekly surveys and EMA:

dep_weekly = pd.read_csv('dep_weekly.csv')
dep_endterm = pd.read_csv('dep_endterm.csv')
ema = pd.read_csv('ema.csv')
platform = pd.read_csv('platform.csv')  # column is 'platform', NOT 'os'

uid = '<user_id>'
user_dep = dep_weekly[dep_weekly['pid'] == uid].copy()
user_dep['date'] = pd.to_datetime(user_dep['date'])
user_endterm = dep_endterm[dep_endterm['pid'] == uid]
user_ema = ema[ema['pid'] == uid].copy()
user_ema['date'] = pd.to_datetime(user_ema['date'])
user_platform = platform[platform['pid'] == uid]
print(f"Platform: {user_platform['platform'].values[0]}")  # use 'platform' not 'os'

Extract and report:

• Platform, weekly depression flag rate (n/total weeks), end-term BDI2 + dep status
• feel_depressed, feel_anxious, dep_weekly_subscale, anx_weekly_subscale with T1/T2/T3 and early/late trends
• EMA: mean, std, min/max, T1/T2/T3 and early/late trend with trajectory classification

Call 2 — Pre/post surveys and personality:

• Pre→Post survey changes for ALL key scales: report Pre value, Post value, % change, ↑↓ arrows, and direction (improved/worsened). Include ALL of: UCLA, SocialFit, 2waySSS (all 4), ERQ reappraisal/suppression, BRS, CHIPS, PSS, STAIS, MAAS, CESD-9, CESD-10
• Personality (BFI10 pre only): extroversion, agreeableness, conscientiousness, neuroticism, openness

Phase 4 — Cross-modal correlation & synthesis (3–4 calls)

These calls must all be completed. They generate the most analytically valuable insights.

Phase 4a call — EMA ↔ Behavioral correlations (Pearson r with p-value and n): Merge EMA with each sensor modality on pid + date (inner join). After merge, dropna() on both columns before computing. Report n for each; skip if n < 5:

• negative_affect_EMA vs intraday_rapids_sumsteps
• negative_affect_EMA vs summary_rapids_avgdurationasleepmain
• negative_affect_EMA vs barnett_hometime
• negative_affect_EMA vs rapids_sumdurationunlock
• negative_affect_EMA vs intraday_rapids_countepisodesedentarybout
• negative_affect_EMA vs barnett_siglocentropy

If EMA is constant (all same value), note: "EMA has zero variance — Pearson correlation is undefined; report n and rely on cross-behavioral correlations for insight."

Also check: negative_affect_EMA vs rapids_uniquedevices (BT unique devices) if n ≥ 5; negative EMA↔unique-devices correlations signal social proximity effects on mood.

Phase 4b call — Cross-behavioral correlations + Peak EMA events: Compute all 6 pairwise correlations (report r, p, n; skip if n < 5 after merge and dropna):

1. Home time ↔ phone unlock count
2. Distance traveled ↔ phone unlock count (apply GPS outlier filter first)
3. Outgoing call count ↔ phone unlock count
4. Outgoing call count ↔ location entropy
5. Incoming call count ↔ distance traveled
6. Location entropy ↔ phone unlock count

All 6 pairs must be reported (even if non-significant); omit only when data is unavailable.

Then compute Peak EMA event analysis — top 3 highest EMA days:

user_ema_sorted = user_ema.sort_values('negative_affect_EMA', ascending=False).head(3)
for _, row in user_ema_sorted.iterrows():
    peak_date = row['date']
    # Compare barnett_disttravelled, barnett_hometime, rapids_sumdurationunlock,
    # intraday_rapids_sumsteps on that day vs. modality means; report % deviation

Phase 4c call — High/low EMA day comparisons + Depression-flagged week behavior:

ema_median = user_ema['negative_affect_EMA'].median()
high_ema_dates = user_ema[user_ema['negative_affect_EMA'] > ema_median]['date']
low_ema_dates = user_ema[user_ema['negative_affect_EMA'] <= ema_median]['date']
# Compare steps, screen time, home time, distance on high vs. low EMA days

If EMA is constant → note no split possible; analyze high vs. low phone usage or other behavioral proxy.

Depression-flagged week comparison: Aggregate daily sensor data to weekly means (group by week). Join on dep_weekly dates (±7 days), then compare depressed vs. non-depressed week means for steps, sleep duration, phone unlocks, home time.

• If ALL weeks are flagged: compare high-symptom vs. low-symptom weeks using feel_depressed or dep_weekly_subscale (split at median).

Phase 4d call — Consolidated temporal trends table: Summarize T1/T2/T3 and early/late changes for ALL key metrics. Use values already computed in per-modality calls (don't recompute from scratch to avoid errors).

Required metrics to include — every row must have T1, T2, T3, Early, Late, %Change, Trajectory:

| Metric | T1 | T2 | T3 | Early | Late | % Change | Trajectory |

Include ALL of: steps, active bout count, sedentary bout count, active/sed ratio, avg sed bout duration; sleep duration, sleep efficiency, bedtime, wake time; outgoing calls, incoming calls, proactivity ratio, distinct contacts, outgoing call duration; distance, radius of gyration, home time, circadian routine, location entropy, transitions, significant places, avg flight duration, std flight duration, avg speed, top-1 location time, top-2 location time, top-3 location time; unlock count, total phone duration, avg session duration, first-use time, home unlocks, study unlocks; BT scans, unique devices, scan efficiency; EMA negative affect, feel_depressed, feel_anxious, dep_weekly_subscale, anx_weekly_subscale.

Table accuracy rule: After filling the table, verify each row: the sign of % change must match the trajectory direction (progressive decline → negative %; progressive increase → positive %). Any mismatch signals a computation error — recheck and correct.

Phase 5 — Data quality (integrate into output)

For each modality, report valid days as n/92. Flag modalities with <20% coverage as "CRITICALLY SPARSE — interpret with caution."

- Highlight discrepancies between self-reported mental health and passive behavioral signals
- Identify dominant behavioral signals (which metrics most distinguish this user's mental state)

Common Pitfalls

1. Platform column: Use user_platform['platform'].values[0] — the column is platform, NOT os. Accessing ['os'] raises a KeyError.

2. Always convert date to datetime before using .dt: user_df['date'] = pd.to_datetime(user_df['date']) — omitting this causes AttributeError: Can only use .dt accessor with datetimelike values.

3. T1/T2/T3 boundary must use the FULL user dataframe: Always compute d_min, d_max = user_df['date'].min(), user_df['date'].max() on all 92 rows BEFORE any NaN filtering. If you compute d_min/d_max after dropna(), the boundaries shift and all T1/T2/T3 values become systematically wrong, producing incorrect trajectory patterns.

4. Home time column: Use barnett_hometime (minutes/day). barnett_homelabel and doryab_homelabel are cluster labels, not durations.

5. Sleep efficiency: summary_rapids_avgefficiencymain is already a percentage (e.g., 93.5). Never multiply by 100.

6. Minute encoding: Bedtime/wake/call times are minutes-since-midnight. Convert: f"{int(m//60):02d}:{int(m%60):02d}". Values ≥ 1440 span next day (e.g., 1500 → 01:00 next day).

7. Survey columns must use exact names with _PRE/_POST suffix. Use df.columns.tolist() on first access; get_field_description does NOT work on survey files.

8. Weekday vs. weekend home time: For students with remote/online classes, weekday home time is often GREATER than weekend (they go out on weekends). Report both values explicitly and note which is higher.

9. Sparse data: Always check df[col].notna().sum() before computing stats. Some users have <14/92 days for some modalities — correlations require >5 overlapping days after inner merge and dropna.

10. Location GPS outliers: barnett_disttravelled and barnett_rog can have extreme GPS errors. Use values[values < values.median() * 10] before averaging; also apply this filter before computing correlations involving distance.

11. Weekly vs. daily merge: dep_weekly is weekly; sensor data is daily. Aggregate daily data into 7-day windows aligned with each dep_weekly date row.

12. EMA correlation requires inner merge on date + dropna: After merge, dropna() on both columns before pearsonr. Report n for each correlation; p-values are unreliable when n < 10. If EMA values are constant (std = 0), note explicitly and skip to cross-behavioral correlations.

13. All weeks flagged for depression: If dep flag rate = 100%, perform high-symptom vs. low-symptom comparison using feel_depressed or dep_weekly_subscale (split at median).

14. Count/duration dissociation is analytically important for both communication and phone usage. Always check whether count (frequency) and duration per session are trending in opposite directions, as this reveals behavioral quality shifts beyond simple quantity changes.

15. Scan efficiency = rapids_countscans / rapids_uniquedevices. Rising efficiency with declining unique devices suggests narrowing social environment.

16. Consolidated table accuracy: Every % change must be verified against the trajectory label. A "progressive decline" row must have a negative % change; a "progressive increase" must be positive. If they disagree, there is a computation error. Recompute using the formula: (late_mean - early_mean) / abs(early_mean) * 100 where early/late are the actual half-study means, NOT T1/T3 proxies.

17. Flight duration analysis: Report both barnett_avgflightdur (avg) and barnett_stdflightdur (variability) with T1/T2/T3 and early/late trends. These measure movement episode durations (not air travel) and their variability is informative about routine consistency.

18. Insight quality: Every generated insight must include specific numeric values, % changes, T1/T2/T3 values (or early/late), trajectory pattern label, and a behavioral interpretation connecting to mental health context. Purely descriptive statements without interpretation or numbers are insufficient. Paradoxes between clinical self-reports and passive behavioral signals are the highest-value findings.
