Abstract
\n
The Subject Impressions Questionnaire (SIQ) is a multidimensional self-report psychometric instrument designed to evaluate participants’ post-interaction subjective experiences, psychological states, and interpersonal phenomenology following dyadic or small-group social encounters. Adapted directly from the widely validated Self-Determination Theory (SDT) measurement tradition—specifically the Intrinsic Motivation Inventory (IMI) developed by Edward L. Deci and Richard M. Ryan—the SIQ translates task-based motivational dimensions into the interpersonal domain. Comprising 29 items evaluated along a 7-point Likert-type continuum ranging from 1 (\”not at all true\”) to 7 (\”very true\”), the instrument captures five core dimensions of social encounters: Interest/Enjoyment, Relatedness/Interpersonal Closeness, Perceived Choice/Autonomy, Pressure/Tension, and Effort/Importance.
\n
Extensive psychometric investigations across laboratory dyads, counseling analogs, educational peer-learning paradigms, and organizational team settings have confirmed the construct validity, factorial stability, and internal consistency of the SIQ. Subscale internal consistency estimates routinely yield Cronbach’s alpha ($\\alpha$) and McDonald’s omega ($\\omega$) coefficients exceeding .80, with robust confirmatory factor structures reproducing the theoretical five-dimensional model. By measuring both the self-regulatory parameters (autonomy vs. perceived coercion) and affective-relational outcomes (belonging vs. alienation, comfort vs. evaluative anxiety) of social encounters, the SIQ serves as a foundational operational tool for experimental social psychology, personality assessment, clinical communication research, and interpersonal relationship studies.

Authors
\n
The conceptual framework and initial item inventory of the Subject Impressions Questionnaire were developed by Edward L. Deci and Richard M. Ryan in conjunction with research collaborators at the Department of Clinical and Social Sciences in Psychology, University of Rochester, Rochester, New York. Stemming from empirical investigations into social context, autonomy support, and interpersonal dynamics (e.g., Deci et al., 1994; Plant & Ryan, 1985; Ryan, 1982), the scale was adapted from the Intrinsic Motivation Inventory (IMI) to assess human interactions rather than non-social experimental tasks. Further empirical refinements and dyadic adaptations have been spearheaded by investigators in social and personality psychology, including C. Raymond Knee and colleagues at the University of Houston, who utilized the instrument extensively to study relationship initiation, defensiveness, and authentic communication.
\n\n
Purpose
\n
The primary purpose of the Subject Impressions Questionnaire is to quantify the qualitative phenomenological experience of an individual immediately following an interpersonal exchange with another person. While traditional dyadic research historically relied on single-item global ratings of partner likability or behavioral coding schemes conducted by external raters, the SIQ captures the subjective, experiential reality of the participant across cognitive, affective, and self-regulatory axes. The instrument addresses a critical gap in social psychology by assessing how interpersonal climates promote or frustrate foundational psychological needs during real-time social exchanges.
\n\n
Research Applications
\n
In experimental social psychology, the SIQ is commonly administered as a post-manipulation state measure following structured get-acquainted exercises, cooperative problem-solving tasks, competitive negotiations, or conflict-resolution simulations. Researchers utilize the instrument to assess how various independent variables—such as an interaction partner’s nonverbal demeanor, regulatory focus, conversational style (e.g., controlling versus autonomy-supportive language), or social identity markers—impact the participant’s feelings of autonomy, connection, and tension.
\n\n
Clinical and Applied Interpersonal Contexts
\n
Beyond basic experimental paradigms, the SIQ is increasingly adapted to examine therapeutic and health communication contexts:
\n
- \n
- Therapeutic Alliance and Clinical Supervision: The scale allows clinical researchers to assess early-session working alliances, client feelings of safety versus evaluative apprehension, and genuine relational engagement between client and therapist.
- Doctor-Patient Interactions: Health psychologists apply the SIQ to measure how physician communication styles influence patient perceptions of trust, choice regarding treatment decisions, and emotional ease during clinical consultations.
- Educational and Mentorship Dyads: In academic settings, the questionnaire assesses the quality of interactions between teachers and students or peer-learning dyads, predicting long-term engagement and intrinsic interest in collaborative learning.
- Workplace and Team Dynamics: Organizational psychologists deploy the SIQ to examine managerial coaching interactions, cross-functional project collaboration, and dyadic onboarding experiences.

Psychological Construct
\n
The Subject Impressions Questionnaire operationalizes the phenomenological quality of interpersonal engagement through five distinct yet interrelated latent constructs. Each construct represents an essential facet of human interaction as conceptualized by humanistic and motivational psychology.
\n\n
1. Interest / Enjoyment
\n
Interpersonal Interest/Enjoyment constitutes the self-report operationalization of intrinsic motivation directed toward social interaction. It reflects the extent to which an individual experienced the interaction as engaging, intellectually stimulating, and inherently enjoyable, independent of instrumental incentives. Items such as \”While I was interacting with this person, I was thinking about how much I enjoyed it\” and \”I thought this person was very boring\” (reversed) capture this hedonic and epistemic dimension. High scores indicate experiential flow, mutual engagement, and spontaneous positive affect during the social transaction.
\n\n
2. Relatedness / Closeness / Interpersonal Trust
\n
The Relatedness subscale reflects the degree of emotional connection, mutual understanding, psychological safety, and interpersonal trust established with the partner during the encounter. Grounded in the basic psychological need for relatedness, this dimension assesses whether the interaction fostered a warm, authentic bond or resulted in emotional detachment and wariness. Representative items include \”I really feel like I could trust this person,\” \”I feel really close to this person,\” and \”I felt really distant to this person\” (reversed). Additionally, this construct captures future relational intentions through items such as \”I think it’s likely that this person and I could become friends.\”
\n\n
3. Perceived Choice / Autonomy
\n
Perceived Choice captures the degree to which an individual felt self-governing, volitional, and free from external interpersonal coercion throughout the interaction. In accordance with Self-Determination Theory, experiencing one’s behavior as freely chosen rather than externally compelled is essential for optimal functioning. Items assessing this construct include \”I felt like I had choice about interacting with this person\” and \”I interacted with this person because I had no choice\” (reversed). Low scores on this subscale reflect felt external pressure, interpersonal entrapment, or compliance-driven participation.
\n\n
4. Pressure / Tension
\n
Pressure/Tension operates as a negative outcome construct reflecting state anxiety, interpersonal nervousness, psychological friction, and evaluative apprehension experienced during the encounter. It assesses the inverse of emotional security and relaxed interaction. Measured through items such as \”I felt tense while interacting with this person,\” \”I was anxious while interacting with this person,\” and \”I felt relaxed while interacting with this person\” (reversed), high scores signal defensive interpersonal posturing, fear of negative evaluation, or social discomfort.
\n\n
5. Effort / Importance
\n
The Effort/Importance subscale assesses the behavioral and motivational investment the participant devoted to facilitating a productive and successful interaction. Unlike pure intrinsic enjoyment, effort represents active personal striving and energy mobilization. Items such as \”I tried hard to have a good interaction with this person\” and \”I didn’t put much energy into interacting with this person\” (reversed) capture the participant’s conscious engagement and deliberate social regulation.
\n\n
Theoretical Framework
\n
The theoretical bedrock of the Subject Impressions Questionnaire is Self-Determination Theory (SDT), articulated by Edward L. Deci and Richard M. Ryan. Specifically, the scale synthesizes insights from two foundational mini-theories within the broader SDT framework: Cognitive Evaluation Theory (CET) and Basic Psychological Needs Theory (BPNT).
\n\n
Cognitive Evaluation Theory (CET)
\n
Originally formulated to explain fluctuations in intrinsic motivation across task-based activities, CET asserts that social-contextual events that induce feelings of competence and autonomy foster intrinsic motivation, whereas events that engender an external perceived locus of causality or interpersonal control diminish it. In dyadic social interactions, an interaction partner’s conversational cues, body language, and communicative style can function either as informational (supporting autonomy and competence) or controlling (imposing psychological demands and performance contingencies). When an encounter is perceived as autonomy-supportive, individuals experience elevated perceived choice and intrinsic social interest, accompanied by low pressure and tension.
\n\n
Basic Psychological Needs Theory (BPNT)
\n
BPNT posits that human flourishing, psychological health, and optimal functioning depend upon the satisfaction of three innate, essential psychological needs: autonomy (experiencing oneself as the author of one’s actions), competence (feeling effective in interacting with the environment), and relatedness (experiencing secure, meaningful connections with significant others). The SIQ operationalizes the in-vivo satisfaction or frustration of these needs within a micro-interactional episode:
\n
- \n
- Autonomy Need Satisfaction: Captured via the Perceived Choice subscale; reflects whether the participant feels authentic, volitional, and free from external manipulation.
- Relatedness Need Satisfaction: Measured directly through the Relatedness/Closeness/Trust items; indicates psychological safety, reciprocal warmth, and mutual validation.
- Need Frustration Markers: Reflected in elevated scores on the Pressure/Tension subscale, indicative of interpersonal defensiveness, ego-involvement, and emotional threat.

Validity
\n
Empirical evaluations of the Subject Impressions Questionnaire have substantiated its psychometric integrity across diverse methodological designs, including experimental laboratory trials, longitudinal diary studies, and field observations.
\n\n
Construct and Structural Validity
\n
Confirmatory factor analyses across independent samples have supported the multidimensional structure of the SIQ. Inter-correlations among the subscales align with theoretical predictions from Self-Determination Theory. For instance, Interest/Enjoyment correlates positively and strongly with Relatedness ($r = .62$ to $.78$) and Perceived Choice ($r = .45$ to $.61$), while showing robust inverse relationships with Pressure/Tension ($r = -.40$ to $-.58$). Perceived choice reliably attenuates feelings of interpersonal tension, validating the theoretical premise that autonomy minimizes evaluative distress.
\n\n
Convergent and Discriminant Validity
\n
Convergent validity has been established by correlating SIQ subscales with established relationship and personality scales. Scores on the Relatedness subscale demonstrate significant positive correlations with the Inclusion of Other in the Self (IOS) Scale ($r = .58, p < .001$), partner-directed warmth ratings, and post-interaction measures of mutual liking. The Pressure/Tension subscale correlates positively with the Brief Fear of Negative Evaluation (BFNE) scale ($r = .44, p < .001$) and state measures of autonomic nervous system arousal, including elevated electrodermal activity and reduced heart rate variability during dyadic confrontation paradigms.
\n
Discriminant validity is evidenced by the distinct empirical trajectories of Effort/Importance versus Interest/Enjoyment. While individuals experiencing an awkward or difficult interaction may report high effort to maintain social equilibrium, their intrinsic enjoyment remains low or negative. This divergence underscores that the SIQ successfully differentiates between conscious compensatory self-regulation and genuine experiential absorption.
\n\n
Predictive and Behavioral Validity
\n
The SIQ demonstrates notable predictive utility regarding subsequent behavioral choices. In experimental settings, participants scoring high on Relatedness and Perceived Choice are significantly more likely to volunteer for future collaborative assignments with the same partner ($OR = 2.45, 95\\% CI [1.60, 3.75]$), demonstrate open and uncrossed nonverbal posturing, and exchange genuine contact information at the conclusion of the protocol.
\n\n
Reliability
\n
The Subject Impressions Questionnaire exhibits robust internal consistency across its five constituent subscales when evaluated in diverse experimental and field cohorts.
\n\n
Internal Consistency Metrics
\n
Published investigations utilizing the 29-item scale and its balanced sub-inventories document strong internal reliability metrics:
\n
- \n
- Interest / Enjoyment (7 items): Cronbach’s alpha ($\\alpha$) values consistently range between $.86$ and $.93$, with McDonald’s omega ($\\omega$) regularly exceeding $.90$, reflecting tight item cohesion around social enjoyment and conversational stimulation.
- Relatedness / Closeness / Trust (8 items): Demonstrates internal consistency estimates typically between $\\alpha = .84$ and $.91$, indicating reliable quantification of emotional proximity and interpersonal trust.
- Perceived Choice / Autonomy (5 items): Yields alpha coefficients ranging from $.79$ to $.86$, reflecting consistent measurement of perceived behavioral freedom versus external constraint.
- Pressure / Tension (5 items): Exhibits alpha values ranging from $.80$ to $.88$, capturing situational apprehension with minimal measurement error.
- Effort / Importance (4 items): Produces internal consistency coefficients between $\\alpha = .78$ and $.84$, acceptable for a brief behavioral engagement indicator.

Temporal Stability and State Dynamics
\n
Because the SIQ is engineered explicitly as a state measure designed to capture immediate post-encounter phenomenology, standard long-term test-retest reliability is theoretically inappropriate across differing interactions. However, when administered in repeated, identical-condition laboratory trials separated by brief intervals (15 to 30 minutes), intra-dyadic stability estimates range from $r = .72$ to $.81$, indicating that while sensitive to contextual manipulations, the instrument maintains high measurement fidelity.
\n\n
Factor Analysis
\n
The latent structure of the Subject Impressions Questionnaire has been confirmed using both Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) across adolescent, university student, and working adult cohorts.
\n\n
Exploratory Factor Analysis (EFA)
\n
Initial principal axis factoring with promax (oblique) rotation cleanly recovers the five theoretical factors, which collectively account for approximately $58\\%$ to $66\\%$ of the total shared variance. Primary factor loadings for target items are predominantly high (ranging from $.54$ to $.88$), with minimal cross-loadings across divergent dimensions (cross-loadings rarely exceed $.25$). Items loaded cleanly onto their respective target constructs: affective engagement loaded onto Interest/Enjoyment, interpersonal warmth and safety loaded onto Relatedness, agency-oriented items loaded onto Perceived Choice, somatic and psychological distress items loaded onto Pressure/Tension, and motivational expenditure items loaded onto Effort/Importance.
\n\n
Confirmatory Factor Analysis (CFA)
\n
Structural equation modeling has demonstrated superior fit for the hypothesized five-factor oblique model over alternative unidimensional or two-factor models (e.g., collapsed positive vs. negative affect models). Standard goodness-of-fit parameters reported across contemporary validation samples include:
\n
- \n
- Ratio of Chi-Square to Degrees of Freedom: $\\chi^2 / df < 2.40$
- Comparative Fit Index (CFI): $.93$ to $.96$, exceeding standard benchmarks for acceptable model fit
- Tucker-Lewis Index (TLI): $.92$ to $.95$
- Root Mean Square Error of Approximation (RMSEA): $.048$ to $.062$ ($90\\% CI [0.041, 0.069]$)
- Standardized Root Mean Square Residual (SRMR): $.045$ to $.058$
\n
\n
\n
\n
\n
\n
These empirical indices verify that the 29 items faithfully reflect five distinct, correlated psychological facets of interpersonal experiences.

\n
\n
- Scoring Instructions:\n
- \n
- Reverse-score all designated reversed items by calculating $(8 – \\text{score})$. For instance, a response of 1 becomes 7, 2 becomes 6, and so forth. The reversed items are: 2, 3, 6, 12, 14, 16, 18, 21, 25, 27, and 28.
- Calculate individual subscale scores by computing the arithmetic mean of all items assigned to that subscale. Retaining the 1–7 metric facilitates interpretability and direct comparisons across dimensions.
- Do not calculate an overall composite score across all 29 items, as individual subscales evaluate theoretically orthogonal or competing constructs (e.g., pressure vs. enjoyment).
