Abstract
Low self-control in childhood is an important predictor of low income, financial problems, poor physical health, substance dependence, single parenthood and criminal offending in adulthood (Moffitt et al. 2011). However, we do not know yet whether children are aware of their own self-control problems and whether their possible sophistication about (awareness of) their self-control problems mitigates the adverse consequences of low self-control.

Behavioral theory predicts that people’s sophistication about their own self-control problems is integral to the choices they make (O’Donoghue and Rabin 1999, 2001). In their seminal theory paper, O’Donoghue and Rabin (1999) draw on the disparity in people’s ideal, predicted and actual choices to identify whether people lack self-control and, if they do, whether they are aware of it. Only few empirical studies directly measure naiveté and sophistication regarding own self-control problems for adults (Augenblick and Rabin 2019; Mandel et al. 2017; Wong 2008 etc.) and we are not aware of any work that does so for children.

Using a sample of about 3,000 households in rural Bangladesh, we assess the effectiveness of the Lions Quest Skills for Growing program in a new data collection about three years after its implementation in grades 2 to 5 in 2019. Lions Quest Skills for Growing is a school-based social and emotional learning (SEL) program that was taught in randomly assigned elementary schools in Bangladesh. In general, SEL programs aim at promoting self-awareness and self-management. Underlying skills that are specifically mentioned in the program documentation are, among others, self-discipline, impulse-control, or goal setting. Here, we examine whether the program affects levels of self-control and possible sophistication about self-control problems. We will use an experiment to measure self-control and the extent of sophistication to classify children as time-consistent, naïve or sophisticated regarding their self-control problems at the individual level. Apart from possible treatment effects, we will test the predictive power of our classification for child outcomes such as study attitude, grades, savings, prosociality, impulsive behavior, or risky behaviors. We can also document age trends and other determinants of self-control problems and sophistication such as gender as well as their relation with other skills and potential intergenerational transmissions.

This new data collection will start as soon as this registration will be reviewed.

Interventions

Intervention(s)
The intervention consists of conveying the content of the “Lions Quest Skills for Growing Program” (SfG) during school hours in participating schools. As a social and emotional learning (SEL) program, SfG aims at helping children to make good decisions, among others in terms of forward-looking behaviors such self-discipline, impulse-control, or goal-setting.

Primary Outcomes

Primary Outcomes (end points)
Classification of individuals (children and subset of their parents) as time-consistent, naïve or sophisticated regarding their self-control problem: three mutually exclusive dummy variables; continuous measures to capture extent of self-control problems and sophistication (partial naiveté)
Primary Outcomes (explanation)
The experiment will be based on a real-effort task for which no specific skills are required: counting zeros in 10x10-tables containing zeros and ones. For classification, three measures will be used: the number of solved tables participants consider ideal for themselves (1. “ideal”), the number of tables they predict to solve correctly (2. “prediction”) and the actual number of correctly solved tables (3. “actual”). More specifically:

1. Participants will be asked for the subjectively ideal plan for themselves (ideal): “What do you consider the ideal plan for yourself: how many tables should you ideally solve correctly?”
2. Participants will be asked for their prediction regarding the number of solved tables (prediction): “What do you think will really happen? How many tables do you predict you will actually solve correctly?”
3. Actual: how many tables has the participant solved correctly?

Participants will be classified as time-consistent if prediction >= ideal and actual >= ideal. Participants will be classified as naïve if prediction >= ideal and actual < ideal. Participants will be classified as sophisticated if prediction < ideal.

The extent of self-control problems will be measured by comparing ideal plan and actual result: (ideal–actual)/ideal. The extent of sophistication with respect to self-control problems will be measured by the share of his or her self-control problem that the participant predicts: (ideal–prediction)/(ideal–actual).

Payments for correctly solved tables will be age-specific.

Experimental Design

Experimental Design
We have a single treatment and a single control group. The 135 primary schools in our sample are divided into 69 treatment and 66 control group schools by stratified randomization. In cooperation with Lions Clubs International, we implemented the social and emotional learning (SEL) program Lions Quest Skills for Growing (PreK-5) in grades 2 to 5 of the 69 treatment schools. The remaining 66 schools in the control group did not receive any treatment.
Experimental Design Details
Not available
Randomization Method
Randomization was done in an office by a computer, more specifically using STATA. In order to gain a balanced treatment-control group setting, we stratified by subdistrict (our schools are located in 11 subdistricts differing in their schooling authorities and hence their educational environment), by distance of the school to its respective subdistrict capital (as a proxy for schooling quality) and village literacy rate. No re-randomization was done but the first draw taken.
Randomization Unit
The treatment was randomized on school level.
Was the treatment clustered?
Yes

Experiment Characteristics

Sample size: planned number of clusters
Treatment was assigned to 69 out of a total of 135 schools (hence, 66 schools in control group). These schools are serving 150 villages that we randomly selected from 11 subdistricts (chosen based on the availability of NGOs willing to collaborate) belonging to four districts of Bangladesh.
Sample size: planned number of observations
3,000 households from the 150 villages that are served by the 135 primary schools in our sample; sampled by selecting at least 20 children from grades 2 to 5 of each school in 2019 – larger samples from schools serving multiple sample villages, e.g. 40 children per school if the school serves two villages. We have a sample that covers about 3,000 pupils attending grades 2 to 5 in 2019 plus information on at least one of their siblings (if they have siblings, the additionally sampled sibling is chosen randomly).
