Abstract

The Problems in Schools Questionnaire (PIS) is a seminal psychometric instrument designed to assess adult orientations toward control versus autonomy support in educational interactions with children. Developed by Edward L. Deci, Allan J. Schwartz, Louise Sheinman, and Richard M. Ryan in 1981, the instrument operationalizes the core tenets of Self-Determination Theory (SDT) within pedagogical contexts. The PIS comprises eight realistic vignettes depicting typical classroom and home behavioral, academic, or social difficulties. Each vignette is followed by four distinct response alternatives corresponding to four regulatory styles: Highly Controlling (HC), Moderately Controlling (MC), Moderately Autonomous (MA), and Highly Autonomous (HA). Respondents evaluate all 32 items using a 7-point Likert-type scale ranging from 1 (“very inappropriate”) to 7 (“very appropriate”). Psychometric evaluations demonstrate sound internal consistency, robust temporal stability across test-retest intervals (r = .70 to .80), and profound construct, convergent, and predictive validity. Elevated autonomy-supportive scores on the PIS systematically correlate with enhanced student intrinsic motivation, self-esteem, perceived academic competence, and conceptual learning, whereas teacher controlling orientations reliably predict student amotivation, anxiety, and school disengagement. This article provides a comprehensive psychometric review of the PIS, detailing its theoretical foundation, structural validity, scoring algorithms, and empirical utility in educational psychology and pedagogical interventions.

Purpose

The primary purpose of the Problems in Schools Questionnaire is to quantitatively capture the interpersonal motivating styles that teachers, parents, and educators adopt when resolving student difficulties in educational environments. In traditional educational research, instructional methodology was frequently conceptualized through narrow operational categories such as direct instruction versus open classrooms. The PIS was established to pivot psychological inquiry away from superficial structural pedagogical forms and toward the underlying functional significance of interpersonal motivational climates.

At its core, the instrument assesses whether an adult tends to support children’s personal initiative, internal volition, and autonomous self-regulation, or conversely, tends to pressure, coerce, control, and manipulate children through extrinsic contingencies and evaluative comparisons. The scale addresses critical educational challenges, including academic underperformance, classroom misbehavior, social isolation, rule violations, and peer conflicts. By assessing adult responses across these multifaceted scenarios, the PIS serves several distinct clinical, diagnostic, and empirical functions:

  • Educational Research: Investigating the systemic antecedents and consequences of classroom motivational climates on student achievement, intrinsic engagement, well-being, and drop-out intentions.
  • Teacher Professional Development: Serving as a pre- and post-intervention diagnostic tool to measure behavioral transformation following training programs centered on autonomy-supportive teaching strategies (e.g., Johnmarshall Reeve‘s autonomy-support interventions).
  • School Psychology & Counseling: Providing clinical consultants with a structured framework to evaluate how institutional pressures, administrative control, and high-stakes standardized testing impact educators’ instructional behaviors.
  • Parental Orientation Assessment: Measuring parenting styles in relation to academic socialization, facilitating cross-contextual comparisons between home and school motivational orientations.

The instrument provides both distinct subscale profiles across four regulatory modalities and a composite Autonomy-Support Index, affording researchers extraordinary analytical flexibility across both person-centered and variable-centered methodological paradigms.

Psychological Construct

The construct assessed by the Problems in Schools Questionnaire is the adult’s interpersonal motivating style along the continuum of autonomy support versus control. Self-Determination Theory postulates that motivating styles are not arbitrary behavioral patterns but reflect deeply ingrained orientations regarding human agency, behavior change, and relational power. The PIS differentiates this continuum into four precisely articulated sub-dimensions:

1. Highly Controlling (HC)

The Highly Controlling style represents an authoritarian, coercive, and pressure-inducing approach to student regulation. Adults exhibiting high HC ratings rely heavily on explicit power assertion, punitive sanctions, enforced compliance, and behavioral mandate. The underlying assumption is that children are intrinsically disinclined toward productive action and require top-down enforcement to conform to institutional expectations. In HC approaches, the adult does not acknowledge the child’s perspective, invalidates negative affect, and uses guilt-inducing or commanding language. For instance, in Item 3, the teacher’s response to an unmotivated student is to “Make him stay after school until that day’s assignments are done,” and in Item 27, a parent resolves a behavioral infraction by deciding to “Give him a good scolding; stealing is something which cannot be tolerated and he has to learn that.”

2. Moderately Controlling (MC)

The Moderately Controlling style attempts to govern child behavior through instrumental extrinsic incentives, social comparisons, and conditional positive regard. Unlike the overt punishment characteristic of HC, MC relies on behaviorist reinforcement schedules, normative grading, competitive spelling bees, point charts, and contingent tangible rewards. Although superficially perceived as positive and supportive, MC strategies remain functionally controlling because they shift the child’s perceived locus of causality from internal to external. Behavior becomes instrumentalized: tasks are pursued exclusively to acquire praise, money, privileges, or superior status over peers. Exemplars include Item 5 (“Increase her allowance and promise her a ten-speed if she continues to improve”) and Item 4 (“Let him see how he compares with the other children in terms of his assignments and encourage him to catch up with the others”).

3. Moderately Autonomous (MA)

The Moderately Autonomous orientation seeks to foster the child’s internalization of values and behavioral standards by emphasizing self-monitoring, structured reflection, and personal effort. While acknowledging the importance of social integration and institutional norms, MA approaches prioritize the child’s own understanding of why certain behaviors are necessary. However, MA retains a moderately prescriptive undertone by projecting the adult’s moral reasoning onto the child rather than fully opening the floor to the child’s internal perspective. Representative items include Item 1 (“She should impress upon him the importance of finishing his assignments since he needs to learn this material for his own good”) and Item 25 (“Talk to him about the consequences of stealing and what it would mean in relation to the other kids”).

4. Highly Autonomous (HA)

The Highly Autonomous style is characterized by comprehensive perspective-taking, active listening, facilitation of personal problem-solving, emotional attunement, and student self-initiation. An HA adult views the child as an inherently active, growth-oriented organism whose challenging behaviors indicate underlying impediments to basic psychological need satisfaction. Rather than issuing unilateral decrees or manipulating rewards, the HA adult provides explanatory rationales, invites self-reflection, validates internal feelings, and co-creates collaborative solutions. In Item 2, the teacher decides to “Let him know that he doesn’t have to finish all of his work now and see if she can help him work out the cause of the listlessness,” and in Item 23, the educator chooses to “Invite her to talk about her relations with the other kids, and encourage her to take small steps when she’s ready.”

Theoretical Framework

The Problems in Schools Questionnaire is conceptually anchored in Self-Determination Theory (SDT), specifically utilizing the theoretical sub-theories of Cognitive Evaluation Theory (CET) and Organismic Integration Theory (OIT) formulated by Edward L. Deci and Richard M. Ryan. SDT conceptualizes human beings as active, growth-oriented organisms with an innate propensity toward psychological integration, intellectual curiosity, and self-actualization. However, this optimal development is not automatic; it requires sustained environmental nutriments in the form of three universal basic psychological needs:

  • Autonomy: The experience of self-endorsement, volition, and ownership over one’s actions, feeling that one is the author of one’s life.
  • Competence: The experience of effectiveness, mastery, and capacity to exercise and expand one’s capabilities within challenging environments.
  • Relatedness: The experience of belonging, mutual care, social connectedness, and feeling valued by significant others.

According to Cognitive Evaluation Theory, interpersonal environments can be either informational or controlling. When instructional interactions are controlling, individuals perceive the functional significance of the interaction as an attempt to coerce them into acting, thinking, or feeling in specified ways. This external pressure undermines the basic need for autonomy, shifts the perceived locus of causality from internal to external, and diminishes intrinsic motivation. Conversely, when an interaction is informational, it communicates competence-relevant feedback within a context of choice, non-judgmental acceptance, and interpersonal warmth, thereby cultivating intrinsic engagement and autonomous self-regulation.

Organismic Integration Theory further clarifies how non-intrinsically interesting behaviors (such as academic homework, classroom behavioral rules, and routine chores) become integrated into the self. OIT posits a continuum of extrinsic motivation ranging from external regulation (compliance via rewards/punishments) to introjection (internal pressure via guilt, ego-involvement, and anxiety), to identification (conscious valuing of the activity), and finally to integration (congruence with core self-values). The PIS was engineered specifically to assess the degree to which an adult’s socialization practices facilitate fully integrated autonomous regulation versus entrenching external and introjected forms of control.

Validity

The psychometric validity of the Problems in Schools Questionnaire has been established across extensive empirical investigations conducted in diverse educational contexts. In their seminal 1981 validation study, Deci, Schwartz, Sheinman, and Ryan administered the PIS to elementary school teachers and prospectively tracked their fourth-through-sixth-grade students across an entire academic school year.

Construct and Convergent Validity

Construct validity is evidenced by the distinct simplex pattern among the four subscales, where adjacent regulatory styles on the theoretical continuum correlate more positively with one another than non-adjacent styles. Specifically, the Highly Autonomous subscale correlates positively with Moderately Autonomous (r ≈ .35 to .45) and correlates negatively with Highly Controlling (r ≈ -.38 to -.52). This simplex matrix confirms that the PIS measures an underlying continuum of self-determination rather than disconnected behavioral traits.

Convergent validity has been established by correlating PIS scores with established psychological indices of teacher personality and instructional beliefs. Teachers scoring high on autonomy support show significant positive correlations with humanistic educational philosophies, pupil-control ideology favoring humanism over custodial control, and high interpersonal empathy. Conversely, controlling scores correlate substantially with authoritarianism, rigid dogmatism, and performance-oriented teaching philosophies.

Predictive and Ecological Criterion Validity

The ecological and predictive validity of the PIS is particularly robust. Deci et al. (1981) demonstrated that within two months of the academic year, children taught by teachers who scored high on autonomy support displayed significantly higher levels of intrinsic motivation (measured via the Children’s Academic Intrinsic Motivation Inventory), elevated self-esteem, and higher perceived academic competence compared to students assigned to controlling teachers. Furthermore, Reeve, Bolt, and Cai (1999) documented strong ecological validity by comparing teachers’ self-reported PIS autonomy-support scores against blind objective behavioral coding of their actual classroom instructional interactions. Teachers classified as autonomy-supportive via the PIS were observed to spend significantly more time listening, allowed students to work at their own pace, offered meaningful rationales for requested tasks, used non-controlling language, and asked significantly more open-ended questions than teachers classified as controlling.

Reliability

The Problems in Schools Questionnaire demonstrates strong psychometric reliability across internal consistency and temporal stability metrics, particularly when evaluated via composite scoring formulations.

Internal Consistency

Because each subscale consists of eight items reflecting diverse classroom scenarios, individual subscale Cronbach’s alpha coefficients reflect modest to moderate internal consistency, which is standard for vignette-based, multidimensional behavioral scales:

  • Highly Autonomous (HA): α = .70 to .76
  • Moderately Autonomous (MA): α = .63 to .70
  • Moderately Controlling (MC): α = .65 to .72
  • Highly Controlling (HC): α = .73 to .80

When the four subscale scores are mathematically synthesized into the overall composite Autonomy-Support Index (calculated using weighted linear contrast coefficients: (2 × HA) + (1 × MA) - (1 × MC) - (2 × HC)), the composite reliability achieves an outstanding internal consistency coefficient typically ranging from α = .80 to .86. This confirms that the aggregated instrument possesses high measurement precision for structural equation modeling and comparative regression analyses.

Test-Retest Temporal Stability

Temporal stability evaluations demonstrate that adult interpersonal motivating styles represent relatively enduring dispositions across time when educational conditions remain unchanged. In the original test-retest investigations by Deci et al. (1981) over a two-month interval, stability coefficients for the four subscales were:

  • Highly Autonomous: r = .80
  • Moderately Autonomous: r = .71
  • Moderately Controlling: r = .76
  • Highly Controlling: r = .78
  • Overall Composite Autonomy-Support Index: r = .83

These values demonstrate excellent reproducibility and ensure that empirical shifts in PIS scores following structured pedagogical training interventions reflect true theoretical development rather than stochastic measurement error.

Factor Analysis

Structural evaluations of the Problems in Schools Questionnaire via Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) validate the theoretical quadripartite continuum postulated by Self-Determination Theory.

Exploratory Factor Structure

Early principal axis factoring with oblimin and varimax rotations revealed that items systematically load onto their designated theoretical dimensions rather than clustering by vignette narrative content. Factor loadings for individual items onto their respective primary dimensions generally exceed .40, with target loadings clustering between .45 and .74. Cross-loadings on divergent dimensions remain minimal, providing robust empirical verification of structural independence.

Confirmatory Factor Analysis & Model Fit

Subsequent psychometric testing utilizing Confirmatory Factor Analysis has evaluated the structural validity of competing models. CFA demonstrates that a four-factor correlated model (representing HC, MC, MA, and HA) consistently outperforms unidimensional or two-factor models (controlling versus autonomous). Typical fit indices reported across contemporary structural modeling studies include:

  • Comparative Fit Index (CFI): .91 to .94
  • Tucker-Lewis Index (TLI): .90 to .93
  • Root Mean Square Error of Approximation (RMSEA): .045 to .058 (90% CI [.040, .064])
  • Standardized Root Mean Square Residual (SRMR): .051 to .062

Furthermore, structural equation modeling validates a quasi-simplex correlation pattern across latent factors: the latent correlation between HA and MA is moderately positive (φ ≈ .42), the correlation between MA and MC is weakly negative to orthogonal (φ ≈ -.12), and the correlation between HA and HC is strongly inverse (φ ≈ -.58). This ordered simplex structure provides rigorous mathematical verification that the PIS operationalizes a continuous underlying continuum of self-determination.

Items of the Scale

Below are the authentic scale items in their original language as published in the standard psychometric validation studies, without modification or translation to preserve instrument validity and reliability:

Instructions: On the following pages you will find a series of vignettes. Each one describes an incident and then lists four ways of responding to the situation. Please read each vignette and then consider each responses in turn. Think about each response option in terms of how appropriate you consider it to be as a means of dealing with the problem described in the vignette. You may might the option to be perfect‚ in other words‚ extremely appropriate in which case you would respond with the number 7‚. You might consider the response highly inappropriate‚ in which case would respond with the number 1. If you find the option reasonable you would select some number between 1 and 7. So think about each option and rate it on the scale shown below. Please rate each of the four options for each vignette. There are eight vignettes with four options for each.

There are no right or wrong ratings on these items. People’s styles differ‚ and we are simply interested in what you consider appropriate given your own style.

Some of the stories ask what you would do as a teacher. Others ask you to respond as if you were giving advice to another teacher or to a parent. Some ask you to respond as if you were the parent. If you are not a parent‚ simply imagine what it would be like for you in that situation.

Response Scale:

1 = very inappropriate | 4 = moderately appropriate | 7 = very appropriate


Vignette A

Jim is an average student who has been working at grade level. During the past two weeks he has appeared listless and has not been participating during reading group. The work he does is accurate but he has not been completing assignments. A phone conversation with his mother revealed no useful information. The most appropriate thing for Jim’s teacher to do is:

  1. She should impress upon him the importance of finishing his assignments since he needs to learn this material for his own good.
  2. Let him know that he doesn’t have to finish all of his work now and see if she can help him work out the cause of the listlessness.
  3. Make him stay after school until that day’s assignments are done.
  4. Let him see how he compares with the other children in terms of his assignments and encourage him to catch up with the others.

Vignette B

At a parent conference last night‚ Mr. and Mrs. Greene were told that their daughter Sarah has made more progress than expected since the time of the last conference. All agree that they hope she continues to improve so that she does not have to repeat the grade (which the Greene’s have been kind of expecting since the last report card). As a result of the conference‚ the Greenes decide to:

  1. Increase her allowance and promise her a ten-speed if she continues to improve.
  2. Tell her that she’s now doing as well as many of the other children in her class.
  3. Tell her about the report‚ letting her know that they’re aware of her increased independence in school and at home.
  4. Continue to emphasize that she has to work hard to get better grades.

Vignette C

Donny loses his temper a lot and has a way of agitating other children. He doesn’t respond well to what you tell him to do and you’re concerned that he won’t learn the social skills he needs. The best thing for you to do with him is:

  1. Emphasize how important it is for him to control himself in order to succeed in school and in other situations.
  2. Put him in a special class which has the structure and reward contingencies which he needs.
  3. Help him see how other children behave in these various situations and praise him for doing the same.
  4. Realize that Donny is probably not getting the attention he needs and start being more responsive to him.

Vignette D

Your son is one of the better players on his junior soccer team which has been winning most of its games. However‚ you are concerned because he just told you he failed his unit spelling test and will have to retake it the day after tomorrow. You decide that the best thing to do is:

  1. Ask him to talk about how he plans to handle the situation.
  2. Tell him he probably ought to decide to forego tomorrow’s game so he can catch up in spelling.
  3. See if others are in the same predicament and suggest he do as much preparation as the others.
  4. Make him miss tomorrow’s game to study; soccer has been interfering too much with his school work.

Vignette E

The Rangers spelling group has been having trouble all year. How could Miss Wilson best help the Rangers?

  1. Have regular spelling bees so that Rangers will be motivated to do as well as the other groups.
  2. Make them drill more and give them special privileges for improvements.
  3. Have each child keep a spelling chart and emphasize how important it is to have a good chart.
  4. Help the group devise ways of learning the words together (skits‚ games‚ and so on).

Vignette F

In your class is a girl named Margy who has been the butt of jokes for years. She is quiet and usually alone. In spite of the efforts of previous teachers‚ Margy has not been accepted by the other children. Your wisdom would guide you to:

  1. Prod her into interactions and provide her with much praise for any social initiative.
  2. Talk to her and emphasize that she should make friends so she’ll be happier.
  3. Invite her to talk about her relations with the other kids‚ and encourage her to take small steps when she’s ready.
  4. Encourage her to observe how other children relate and to join in with them.

Vignette G

For the past few weeks things have been disappearing from the teacher’s desk and lunch money has been taken from some of the children’s desks. Today‚ Marvin was seen by the teacher taking a silver dollar paperweight from her desk. The teacher phoned Marvin’s mother and spoke to her about this incident. Although the teacher suspects that Marvin has been responsible for the other thefts‚ she mentioned only the one and assured the mother that she’ll keep a close eye on Marvin. The best thing for the mother to do is:

  1. Talk to him about the consequences of stealing and what it would mean in relation to the other kids.
  2. Talk to him about it‚ expressing her confidence in him and attempting to understand why he did it.
  3. Give him a good scolding; stealing is something which cannot be tolerated and he has to learn that.
  4. Emphasize that it was wrong and have him apologize to the teacher and promise not to do it again.

Vignette H

Your child has been getting average grades‚ and you’d like to see her improve. A useful approach might be to:

  1. Encourage her to talk about her report card and what it means for her.
  2. Go over the report card with her; point out where she stands in the class.
  3. Stress that she should do better; she’ll never get into college with grades like these.
  4. Offer her a dollar for every A and 50 cents for every B on future report cards.
