Mood Patterns and the People in Your Life
Updated: 1 day ago
Ask someone what shaped their mood today and they will usually name an event. The research says they should name a person. Who you spent the day with is one of the strongest things that moves how a day feels, and it is one of the easiest things to record.
The data
In 2004, Daniel Kahneman, Alan Krueger, and colleagues published the Day Reconstruction Method in the journal Science. They asked 909 employed women in Texas to break the previous day into episodes, say who they were with in each one, and rate how they felt during it on a 0 to 6 scale. Positive affect averaged happy, warm/friendly, and enjoying myself. Negative affect averaged six feelings, including frustrated, depressed/blue, and worried/anxious. The paper's Table 1 reports both averages for each type of companion, plus the hours a day spent with them.
We took those published values and computed one thing the table does not show: net affect, positive minus negative, for each companion. We then weighted it by hours per day to see where the day's emotional weight actually sits.
Net mood by companion
Net affect (positive minus negative), highest to lowest:
Friends: 4.36 minus 0.67 = 3.69
Relatives: 4.17 minus 0.80 = 3.37
Spouse or partner: 4.11 minus 0.79 = 3.32
Children: 4.04 minus 0.75 = 3.29
Clients or customers: 3.79 minus 0.95 = 2.84
Co-workers: 3.76 minus 0.92 = 2.84
Alone: 3.41 minus 0.69 = 2.72
Boss: 3.52 minus 1.09 = 2.43
Three things stand out.
First, the gap between the top and the bottom is large. Time with friends scores 1.26 points higher on net affect than time with the boss, on a scale where the duration-weighted average for positive feeling across the whole day was 3.89. That is a bigger spread than most activities produce.
Second, alone is not the bottom, and it is not what it looks like. Being alone had the lowest positive score of any companion (3.41) but also one of the lowest negative scores (0.69, essentially tied with friends). Alone time is flat rather than bad. The boss is the only companion whose negative score passed 1.0.
Third, the ranking of work companions is the reverse of the ranking of hours. The women spent 5.7 hours a day with co-workers, 4.5 with clients, and 2.4 with the boss, against 2.6 hours with friends and 1.0 with relatives. Weighting net affect by hours, the single largest contribution to the day's total feeling came from co-workers (5.7 hours at 2.84), simply because that is where the hours were. Friends contributed less in total despite the highest per-hour score, because there were fewer of those hours.
What this means in practice
The lesson is not only "see your friends more," though that holds up. It is that the people variable is both powerful and, for most of a working day, fixed. You cannot swap your co-workers for your friends between 9 and 5. What you can change is the margin: the 2.6 hours with friends, the 3.4 hours alone, who you call on the way home.
Later work with a much larger sample reached the same conclusion from a different angle. An analysis of more than 520,000 Gallup daily-poll interviews found Americans spend 7.1 hours socially with friends or family on weekend days versus 5.4 on weekdays, and that the difference explains a large share of why weekends feel better. The paper is available from the National Bureau of Economic Research.
There is a second, more personal point. These are averages across 909 people in one state two decades ago. Your own ranking will differ. One relative might be your best company. One friend might reliably leave you drained. Population data can tell you that companions matter. It cannot tell you which of yours do.
Finding your own ranking
This is the pattern a few words a day captures best. "Good, dinner with Sam." "Drained, argued with my sister again." After two weeks, the names that show up in your low entries and the names that show up in your good ones are a personal version of the table above.
Mood Textapp looks for exactly that. Reply to the evening check-in with whatever is true, and when you ask for your patterns it will tell you when a name keeps appearing on your low days, in the spirit of "4th low day this month, 3 of them mentioned your sister." It is counting, not judgment. A pattern is a prompt to think about a relationship, not a verdict on it.
If a relationship leaves you feeling unsafe, or if low days have become most days, talk to someone who can help, starting with a doctor or therapist. If you are in crisis, call or text 988 to reach the 988 Suicide & Crisis Lifeline.
