Contribution
It tests SDT’s three needs against seven rivals drawn from Maslow, Epstein, terror management, hedonism and the “American dream” (physical thriving, security, self-esteem, self-actualization–meaning, pleasure–stimulation, money–luxury, popularity–influence), using two criteria: how salient each is in people’s most satisfying events, and how well it predicts the event’s affect. The three SDT needs pass both, in the USA and South Korea, over three time frames; so does self-esteem, which SDT does not count (pp. 325–327, 335–337).
Key insight
A need should be both what people find in their best experiences and what makes those experiences feel good. Asking people to recall the single most satisfying event and rate what it contained gives a natural-language window on needs, as lexical studies did for traits (p. 326). By that window self-esteem is as fundamental as autonomy, competence and relatedness, and more predictive than any of them in two of three US samples.
Assumptions
- Needs are “necessary inputs” for thriving, not motives, and are identified by the two criteria (pp. 325–327). The second criterion assumes “that satisfied needs should promote well-being and psychological thriving in the same way that proper fertilization promotes the growth of plants” (p. 327).
- Each candidate is three self-report items completing “During this event I felt …”, rated 1–5 (Table 1). Self-esteem’s items are “That I had many positive qualities”, “Quite satisfied with who I am”, “A strong sense of self-respect”.
- Affect is the event’s PANAS, positive minus negative as affect balance (p. 328).
- Need preference (Study 1) is a pairwise-comparison measure of the ten, after Oishi et al. 1998 (pp. 328–329). Its autonomy definition reads “Autonomy–independence: Feeling like you are the cause of your own actions” (Appendix).
- Retrospective recall of one event; university students.
Key results
Study 1: most satisfying event of the last month (N = 315 of 322; pp. 327–330)
- A principal-components analysis of the 30 items gave nine factors, not ten: pleasure–stimulation and physical thriving loaded together (Table 1).
- Salience (Table 2): self-esteem 4.08, relatedness 3.99, autonomy 3.98, competence 3.74, then pleasure–stimulation 3.53 … money–luxury 2.37.
- Correlations with affect balance (Table 3): self-esteem .43, autonomy .34, competence .26, relatedness .23 … money–luxury −.12.
- Three SDT needs alone on affect balance: autonomy β = .23, competence .21, relatedness .14. All ten simultaneously: autonomy .17, competence .12, relatedness .12, self-esteem .28, money–luxury −.17 (p. 330).
- Need preference did not moderate: the ten product terms ΔR² = .03, p = .21; only self-actualization’s was significant (p. 330).
Study 2: last week, USA (N = 152) and South Korea (N = 200) (pp. 330–333)
- Salience (Table 4): US self-esteem 3.65 first; Korea relatedness 3.65 first and self-esteem 3.23 second; Koreans higher on relatedness, security, pleasure and money, lower on self-esteem.
- All ten on affect balance: US autonomy .29, competence .25, relatedness .21, nothing else; Korea autonomy .26, relatedness .20, self-esteem .23, security .25, money–luxury −.22, competence .10 (ns) (p. 332).
- In Korea competence correlated positively with negative affect (.16, Table 5).
- Culture × need interactions: none significant, ΔR² = .02, p = .34.
Study 3: last semester, satisfying and unsatisfying (N = 233; pp. 333–335)
- Satisfying event, salience (Table 6): self-esteem 3.97, autonomy 3.77, competence 3.73, relatedness 3.66 … money–luxury 2.24. All ten on affect balance: self-esteem .38, autonomy .17, relatedness .12 (marginal), competence .00, money–luxury −.14.
- Unsatisfying event, “what was missing”: competence 3.02 most absent, then autonomy 2.86, security 2.77, relatedness and self-esteem 2.63–2.66. Missing security correlated .50 with negative affect, the largest (Table 7). All ten on affect balance: competence −.22, security −.26, self-esteem −.18 (p. 335).
The authors’ conclusions (pp. 335–337)
- “If one were to pick a single need that is most important to satisfy in the United States, the current data suggest it would be self-esteem” (p. 336).
- “Self-determination theory does not have a way to account for these results, except perhaps to consider self-esteem as a well-being outcome rather than a predictor. … it might be imprudent to consign self-esteem to the outcome category rather than considering it as a need in its own right.” Competence and self-esteem “were empirically separable”. “There may be four fundamental psychological needs, not three” (p. 336).
- A two-tier reading: security a “deficiency” need, autonomy and relatedness “enhancement” needs, self-esteem and competence at both levels (pp. 336–337).
Claims
| id | claim | strength | support |
|---|---|---|---|
| C1 | Autonomy, competence, relatedness and self-esteem are the most salient qualities of satisfying events | moderate | all four samples, Tables 2, 4, 6 |
| C2 | They are the strongest unique predictors of event affect among ten candidates | moderate, with exceptions | competence ns in Korea and Study 3; self-esteem ns in US Study 2 |
| C3 | Self-esteem is a fourth need | weak | the authors’ “preliminary conclusion”; criteria are self-report and self-esteem items overlap with positive affect |
| C4 | Money–luxury and popularity–influence are not needs | moderate by these criteria | lowest salience; negative unique predictor of affect in three of four samples |
| C5 | The needs are universal across the two cultures, with different orderings | weak–moderate | no culture × need interactions, one collectivist sample |
| C6 | Need preferences do not moderate the needs’ effects | weak | null interactions; a footnote notes “it is difficult to draw conclusions from null effects” (fn. 4) |
| C7 | Security is a deficiency need | weak | Study 3’s unsatisfying events only |
Concepts
- Psychological need (here) — “particular qualities of experience that all people require to thrive” (p. 325); “evolved desires” pulling people “toward the same general experiences and incentives” (p. 336).
- Salience criterion and affect criterion — the two tests (pp. 326–327).
- Deficiency vs enhancement needs — after Maslow: what must be met to avoid ill-being against what yields well-being (pp. 333, 336–337).
Connections
- The nine-item autonomy, competence and relatedness subset became Study 1’s measure in Chen et al. 2015 (LIT-2000), which criticizes this paper for not testing measurement equivalence.
- Chirkov et al. 2003 (LIT-1989) cites it as evidence that event autonomy predicts well-being in Korea as in the USA.
- It answers Iyengar and Lepper 1999 (LIT-1949) and Markus et al. 1996 on autonomy’s universality (p. 333).
- Kasser and Ryan 1993, 1996 for the “dark side” of the American dream.
Bearing on the record
- The registration and NOTE-440’s reply, corrected. LIT-1966 says “self-esteem performs strongly. NOTE-440 holds SDT’s reply, that self-esteem is derivative.” The paper’s own authors, Kasser and Sheldon among SDT’s central researchers, considered that reply in the paper and rejected it: treating self-esteem as an outcome would be “imprudent”, and the “preliminary conclusion” is four needs (p. 336). SDT’s later position (NOTE-440, pp. 5, 7) is a reply to its own authors’ 2001 conclusion, not to an outside critic.
- QUESTION-369: the paper names the question’s problem in its own case. Self-esteem can be a need or “a well-being outcome rather than a predictor”; the data cannot decide, because the criterion is affect and the self-esteem items (“Quite satisfied with who I am”) read like well-being. The same holds for the three SDT needs, with less vividness. The paper’s two criteria are both self-reports of the same remembered event, so convergence between them is not independent confirmation. It is the clearest worked instance in the record of the interdefinition NOTE-439 flags.
- Its own measure of autonomy preference labels autonomy “autonomy–independence” (Appendix), the conflation Chirkov et al. (LIT-1989) argue against two years later.
- LIT-1983 and LIT-1980 test beneficence by the frustration criterion; this paper’s deficiency analysis (Study 3) is an early form of that criterion, and on it autonomy and relatedness “did not as strongly influence the affect associated with unsatisfying events” (p. 337).
- THEORY-052: Study 3’s “missing” ratings are an early, event-level measure of something like frustration; competence and security, not all three SDT needs, carried the unique variance there.
- Filed from it: THEORY-1310 (Active).
- No instruction for machine-learning practice.
Limitations
- Students only; retrospective recall of one event; self-reported outcomes; “rare-but-powerful experiences” probably missed (the authors’, p. 337).
- Three items per candidate; the ten-factor structure failed (nine factors), and competence item 3 cross-loaded .44 on self-esteem (fn. 2).
- Self-esteem items overlap in content with positive affect, which inflates its affect criterion; the same risk for the other candidates is smaller but not zero.
- Many tests; Study 1’s salience comparisons at p ≤ .01, but regressions not corrected.
- One collectivist culture.
Open questions
- Does self-esteem predict outcomes that are not affect reports (functioning, health), beyond the three needs?
- Can self-esteem be satisfied independently of competence and relatedness, or is it, as SDT later argued, their by-product? A design that manipulates one and measures the others would say.
- Does the four-need result survive measurement-equivalence testing across cultures (Chen et al.’s objection)?
