Participants were 50 adults who completed a five-minute interaction session, during which they were observed and assessed using the IRSA. Furthermore, health social professionals evaluated participants’ social competence using practical assessment. Results indicated a moderately high correlation (r = 0.58) between IRSA scores and professionals’ practical evaluation. The Cronbach’s alpha value was 0.89. Thus, the IRSA appears to measure social competence with high validity and reliability. Since the IRSA provides context-based evidence of social competence development, this measure should be useful for evaluating the various features of social interaction in a practical setting. Keywords Social Competence, Interaction, Evaluation, Scale, Adult 1. Introduction Social competence has been defined as a dimension of social intelligence[1, 2]. Social intelligence is the ability to engage in adaptive and positive social interactions, which is theoretically distinct from general academic intelligence. However, it is often difficult to discriminate social intelligence from general intelligence. Historically, social intelligence has somewhat overlapped with social competence, which is determined by the complex interaction between the individual, his/her home and school environments, peer relationships, and the larger sociocultural environment[3]. Social competence is broadly defined as the ability to understand others in the context of a social interaction and engage in smooth communication. Thus, social competence should be evaluated by the interaction between the individual and his/her social environment[4]. Dealing with social stress among adults who display impulsive and maladjusted behavior requires society to * Corresponding author: tokieanme@gmail.com (Tokie Anme) Published online at https://www.eduzhai.net Copyright © 2014 Scientific & Academic Publishing. All Rights Reserved prepare appropriate support systems and environments for those individuals. Researchers have been engaged in the study of social competence development for decades. However, methodologies that consider individuals in conjunction with their social environment across developmental stages are not yet well developed. We developed four social competence scales for different stages of lifespan development: (1) the Interaction Rating Scale (IRS), which is an observation method for child– caregiver interactions that assesses children under 8 years old[5,6]; (2) the Interaction Rating Scale between Children (IRSC), which is an observation method for child–child interactions that assesses children 3 to 18 years old[7]; (3) the Interaction Rating Scale Advanced (IRSA), which is an observation method for adult–adult interactions that assess individuals over 15 years old[8]; and (4) the Social Skill Scale (SSS), which uses an enumerator method to assess children under 7 years old[9]. These scales, based on accumulated knowledge from the developmental sciences, have focused on measuring the quality of an environment where positive interactions with the environment are significantly related to healthy development. Two instruments assessing the home environment, namely the Home Observation for Measurement of the Environment (HOME)[10] and the Index of Child Care Environment 26 Tokie Anme et al.: Validity and Reliability of the Interaction Rating Scale Advanced (IRSA) as an Index of Social Competence Development (ICCE)[11] are often used in research related to the right to withdraw from the study at any time.

Furthermore, all video picture data natural settings, including one’s emotional and verbal were stored on a disk, which was password protected.

The HOME is a very popular 2.2. Measures measure, having been used in more than 100 countries. The IRSA is a 92-item instrument designed as a brief but Several observation-based social competence measures comprehensive observation measure that assesses basic have been developed that focus on specific areas of social social competence for individuals over the age of 15. Social interactions; these measures include the Mediated Learning competence is examined through five-minute observations Experience Rating Scale (MLERS), which deals with of a social interaction. One advantage of the IRSA is that teacher–student interactions[12]; the Social Skills Rating evaluations of interactions can be completed in a short System (SSRS), which is used to examine caregiver–child period within normal, daily situations. interactions[13]; and the Autism Diagnostic Observation The IRSA includes a behavioral score and 6 subscales Schedule-Generic (ADOS-G)[14] and Childhood Autism scores that combined provide an impression score: Rating-Scale (CARS), which are used to assess social “self-control,” “expressivity,” “sensitivity,” “assertiveness,” competence individuals suspected of having an autism “responsiveness,” and “regulation” (Appendix 1).

In order to comply with ethical standards behaviors. Behaviors during the interaction were coded as before conducting the research, all participants signed follows. If the participant displayed the behavior described informed consent forms and were made aware that they had in the item, a score of 1 was given; conversely, if the Public Health Research 2014, 4(1): 25-30 27 participant failed to display the behavior described in the item, a score of 0 was given. The total score was the summed scores of all 6 subscales. A higher score indicated a higher level of social competence. Two health social professionals then evaluated social competence based on observations of the practical assessment using the IRSA impression items. The means of the six subscale impression scores were calculated. Figure 1. Video recording from four directions 3. Results The correlation analysis was used to validate the use of this measure to assess social competence (i.e., how well the IRSA assesses behaviors in conjunction with professional reports). Figure 2. Correlation between IRSA scores and professional evaluations Figure 2 shows the correlation between the total score on the IRSA and professionals’ practical evaluations of the interactions. Results suggest a moderately high correlation (r = 0.58, p < 0.001) between IRSA scores and professionals’ practical evaluations. No significant gender or age differences were found on the IRSA subscales. The internal consistency of the IRSA, as measured by Cronbach’s alpha, was 0.89. 4. Discussion This current study provides a measure (IRSA) that can assess social competence with moderately high validity and reliability. The social competence scale for child–caregiver interactions (IRS)[5,6] and child–child interactions scale (IRSC)[7] have already shown adequate reliability, validity, feasibility, and practical utility for examining social interactions over time. It is meaningful that the IRSA can be used to assess social competence continuously along a lifespan developmental continuum. Several studies have indicated that observational outcomes differ from self-administrated outcomes because self-optimism produces biases that provide favorable evaluations for the self[21,22]. Observation-based scale is essential to understand the social competence development actually used in one’s life. Social skills play a role in how well an individual copes with stress. Thus, possessing adaptive social skills should be just as important to social adjustment and well-being as is psychological health[23]. The IRSA may prove useful in research on psychological stress and coping by having the ability to examine individuals' abilities to cope with stress [24]. Additionally, the IRSA could be used as part of communication skills training programs for health care professionals[25]. The strength of the IRSA is the ability to assess objective social competence throughout the lifespan. Additionally, the IRSA is easy to use in practice because it is highly adaptable to various age groups. Furthermore, the framework of the IRSA is based on the most common measurement paradigms used around the world; this makes it easier to use this measure within international comparative studies. Additionally, the 6 subscales are based on several categories that are widely used in research on social competence indicators. Even though the IRSA has some valuable strengths, it is also important to acknowledge the IRSA’s limitations. First, the IRSA was assessed with only 50 participants in the current study. Thus, the generalizability of the present results should be taken with caution. Second, the IRSA subscales might not cover all the dimensions of social competence, even though we used the most common components of social competence addressed in previous studies. Despite these limitations, the IRSA appears to be a consistent, valid screening instrument that reflects attributes of social interactions. We have already started to employ the IRSA for assessing individuals with autism in order to characterize behavioral features and the evaluation of treatment outcomes. Further research should enhance the potential to reveal additional features of social interaction development that will be of use to both practitioners and researchers. 28 Tokie Anme et al.: Validity and Reliability of the Interaction Rating Scale Advanced (IRSA) as an Index of Social Competence Development 5. Conclusions ACKNOWLEDGEMENTS This study indicated a moderately high correlation (r = 0.58) between IRSA scores and professionals’ practical evaluation. The Cronbach’s alpha value was 0.89. Thus, the IRSA appears to measure social competence with high validity and reliability. Since the IRSA provides context-based evidence of social competence development, it should be useful for evaluating the various features of social interaction in a practical setting, continuously along a lifespan developmental continuum.
