More and more social surveys are conducted online now than ever. Therefore, we investigated a method, planting instructed response items (IRIs) in a survey, to eliminate inattentive respondents as a necessary screening. Two web surveys were conducted; there were four IRIs in study 1 (n=2,490) and three in study 2 (n=2,000). The objectives were twofold; finding an appropriate number of IRIs in a web survey and finding the differences between the two groups, the original and the screened data, categorized by IRIs. In study 1, of the respondents who passed the first three IRIs, 1,935 out of 2,490 were considered attentive; the rest (555) were eliminated from the data analysis based on the response tree analysis. The two groups were compared on the quality-of-life scale with 24 items, with all respondents and only the attentive. The difference in mean scores between the two groups was statistically significant. Still, the difference was minor because of the shared respondents, 1,935 respondents between the two groups. The item characteristic curves from the 2-parameter logistic model were compared between the attentive (n=1,935) and the inattentive (n=555) respondents. The differences were distinctively visible, and the decision to eliminate 555 respondents was supported. In study 2, the birthday was asked and used to calculate the age. Then, the calculated age was checked by comparing the provided age by the web survey company. The rates of correct responses increased monotonically with higher levels of attentiveness. We conclude that evidence indicates IRIs function well for detecting inattentive respondents. We also tentatively recommend that three IRIs in a survey work well to detect inattentive respondents. Finally, the treatment of the respondents with the gray-zone attentiveness was discussed.

A Japanese Version of the Personal Relative Deprivation Scale (J-PRDS): Development and validation of the J-PRDS

Ohno, H., Masuda, S. & Maeno, T.

Current Psychology 42 15465 - 15474 2022.02

Research paper (scientific journal), Joint Work, Accepted

This study developed and validated a 5-item Japanese translation of the Personal Relative Deprivation Scale (J-PRDS5), originally developed in English by Callan et al. Personality and Social Psychology Bulletin, 34, 1514–1529, (2008), Callan et al. Journal of Personality and Social Psychology, 101, 955–973, (2011) to measure feelings of resentment and dissatisfaction stemming from the belief that one has been deprived of a desired or deserved outcome as compared to others similar to them. Most studies on feelings of personal relative deprivation (PRD) have included Western participants and no such studies have been conducted in Japan. To bridge this gap, we conducted a factor analysis of the J-PRDS5’s items, which demonstrated a single-factor structure consistent with Western studies. Through validation of the scale for Japan, our version (J-PRDS5) exhibited high internal consistency. In contrast to feelings of PRD, subjective socioeconomic status (SSS) focuses on cognitive appraisals by comparing oneself to all people in the same society. Higher J-PRDS5 scores were significantly and negatively correlated with SSS, and lower J-PRDS5 scores and higher SSS scores were significantly correlated with higher self-esteem, general health, and subjective well-being (SWB). Based on a mediation analysis, we found that PRD mediated the relationship between SSS and self-esteem, general health, and SWB. Our study is the first to assess individuals’ feelings of PRD in Japan, and our findings suggest that reducing feelings of PRD may improve individuals’ health and happiness.

　小児集中治療室(PICU)に子どもが入室した両親に生じる心理的問題の状況を明らかにするために，不安，抑うつ，PTSDの既存尺度を用いた質問紙調査を行った。調査は，子どもが入室中と退室から3か月後の2時点で実施，日本国内12施設のPICUと6施設の小児が入室する成人ICUで，第1回目(入室中)の質問紙に237人，第2回目(退室後3ヶ月)の質問紙に142人の両親から回答を得た。その結果，子どもがPICUおよび成人ICUに入室した両親のうち，入室中の時点で25.4%～34.3%の両親に，退室後3か月の時点で11.6%～20.4%の両親に，不安，抑うつ，PTSDが生じており，子どもがPICUに入室した両親は，子どもが成人ICUに入室した両親よりも心理的問題が生じる度合が高かった。本邦においても，欧米の先行研究結果と同様に，PICU入室児の両親に心理的問題が生じており，今後，その影響因子の検討が必要である。また，入室中の不安，抑うつ，PTSD得点がカットオフ値以上であった両親の方が，カットオフ値未満の両親よりも，退室後3か月の同尺度得点がカットオフ値以上であるリスクが高い一方で，退室後3か月に不安，抑うつ，PTSD得点がカットオフ値以上の両親には，入室中の同尺度得点がカットオフ値未満であった両親が17.9%～50.0%含まれていたことから，入室中の時点で，一見問題がなさそうに見える両親であっても，退室後に心理的問題が生じる可能性が示唆された。

Certain participants are insincere when responding to questionnaires. Two current approaches for detecting unmotivated or dishonest respondents, the instructional manipulation check (IMC), and the seriousness check, were examined. We also attempted to improve the quality of survey responses by asking respondents to take an oath that they would be serious before they started answering the questionnaire (TO). The respondents in two Web surveys were randomly assigned to one of four versions of the questionnaire. The main results indicated that (a) response quality tended to improve when respondents who did not follow instructions were excluded from the sample; and (b) respondents that who took an oath to answer seriously chose fewer “don’t know” options, straight line responses, and midpoint responses than the control group, suggesting that respondents behaved consistently with their initial commitment. The results indicate that although IMC is superior for improving data quality, techniques for deterring less serious responses including TO were desirable in that they did not reduce the sample size.

Research paper (scientific journal), Single Work, Accepted

Response biases such as midpoint responses denigrate the validity of research conclusions. In this article, the authors’ experimental studies on midpoint responses are introduced. For example, these studies have suggested that respondents with low motivation tend to choose the middle category. This could partially explain why fewer people in Japan have reported being happy. Another study by the authors demonstrated that over responding increases middle category responses in a phenomenon that is seemingly similar to habituation. In addition, the availability of response time and eye tracking data among others are discussed. With the growth of web surveys, it has become easy to experimentally investigate survey response behaviors. Therefore, collaborations between experimental psychologists and survey researchers would be helpful to improve the quality of surveys.

多くの項目が設けられた調査票に回答することで、回答にどのような変化が生じるのかを検討した。まず研究1で、ランダムな設問順を含む異なる複数の回答フォームを設けて検討したところ、項目の内容や配置の仕方にかかわらず、尺度の後半で中間選択が増加した。研究2では、心理尺度の項目を半数ずつ、見かけ上2つに分割した場合に、中間選択数に変化が見られるかどうかを検討した。結果は尺度を分割することで、後半に配置された項目での中間回答数は一時的に低下するか、増加傾向が抑えられた。しかしその効果は非常に小さいか、あってもすぐに消失し、その後中間選択数が増加していった。

Internet surveys are currently used in many academic and marketing research ﬁelds. However, the results for these surveys occasionally show traces of response bias. In our study, we analyzed how response bias appears in lengthy
preference judgments. 1042 respondents participated in lengthy sequential preference judgments. Three stimuli series were used: scene pictures, Attneave nonsense shapes, and point-symmetric ﬁgures. One hundred stimuli were selected for each series and individually displayed on a computer screen, with presentation order randomized for each respondent. Respondents were then asked to rate their degree of preference for each stimulus. Mean preference scores increased over the ﬁrst 10–20 trials, then, gradually decreased from the middle to the last trial. Furthermore, participants tended to produce the maximum and minimum score during early trials. These results demonstrated that response bias can be a function of presentation order.

Respondents with low motivation tend to choose middle category: Survey questions on happiness in Japan

Some studies have shown low proportions of Japanese people rating their lives as happy. However, most surveys in Japan revealed that response distributions for subjective well-being items indicated excessive blips in middle categories. In this study, participants responded to four items that were designed to detect careless or unmotivated respondents; these items instructed respondents to choose a certain response category. Of the study’s respondents, about 40% failed to follow instructions for at least one of the four items. Besides, they often chose middle categories for well-being items. When those who did not follow instructions were excluded from the complete sample, middle categories showed low or no blips, and the proportion of respondents with high rating scores increased. Thus, this study suggested that one reason for reportedly low proportions of happy people in Japan was respondents who were not diligent in reading items.

Certain participants are insincere, or careless when they respond to questionnaires. To identify such participants, we included three items in a questionnaire that instructed participants to choose a particular response category. Nurses (N=1000) responded to this questionnaire in a Web survey. Of these, 120 participants failed to follow the instructions for at least one item (non-followers). Analyzing their responses indicated the following: (a) non-followers were more likely to give identical, or midpoint responses; (b) the correlations between their responses to regular and reversed items were low or positive, and their responses to scales containing reversed items tended to show lower internal consistency; finally (c) the mean scores of non-followers were closer to the midpoint of the scale, regardless of whether the scale included reversed items. One reason that including reversed items lead to lower internal consistency could be because participants occasionally missed responding to these items. However, the results suggested that non-followers were not diligent in responding to even regular items, and merely deleting reversed items from scales was insufficient to assure accurate results.

The Maslach Burnout Inventory (MBI) is the golden standard for the assessment of burnout. But,the MBI comprises three subscales(exhaustion,cynicism,professional efficacy), so interpretation can be difficult. There is no generally accepted classification of burnout. We aimed at classifying scores on the MBI-General Survey according to the exhaustion+1 criterion and applying neural test theory to the classification of results. We obtained data from a mental health examination we had performed in 2008 targeting on 1553 employees of a computer industry firm. The valid data for 1042 employees (669 men,373women) were used in the present analysis. The results suggested five classifications. Those meeting the exhaustion+1 criterion (a high score for exhaustion and a high score for cynicism, or a low score for professional efficacy) were judged as experiencing burnout, and those who additionally have both a high score for cynicism and a low score for professional efficacy were considered as experiencing severe burnout. Those with only a high exhaustion score were simply classified as being very exhausted. We also suggested increased attention those without exhaustion but with high cynicism scores as they were at risk of depression. Those falling under none of the above were considered healthy.

本研究は、卒後の新人研修において実施されたアサーション・トレーニングが新人看護師のアサーティブな態度やスキルすなわちアサーションの向上と、自尊感情に及ぼす効果を検証するとともに、アサーティブな態度やアサーションスキルが入職して早期に見られるバーンアウトや抑うつ、離職意図の軽減に及ぼす効果などを3つの研究によって明らかにした。
その結果、本研究で実施したアサーション・トレーニングのプログラムは、新人看護師のアサーション・マインドすなわちアサーティブな態度・信念とアサーティブな行動・技能すなわちアサーションスキルの両方を向上させうることが示された。また、アサーション・トレーニングはアサーションの向上とともに、自尊感情も高める効果を有していた。さらに、アサーティブな態度・信念は入職早期の個人的達成感の向上や抑うつの軽減に寄与していた。
これらの結果について考察を加えるとともに、新人看護師など対人援助職の卒後教育と新人研修のプログラムや心理教育のあり方について提案を行った。
