本研究の目的は、ソーシャルネットワークインセンティブと経済的インセンティブを併用することが経済的インセンティブ単独と比べて、介入中および介入後で女性高齢者の身体活動量とソーシャルキャピタルに顕著な変化に導くかどうかを確かめることである。 |
The main goal of this study was to ascertain whether combining financial incentives with social network incentives could lead to more significant changes in physical activity and social capital among elderly women, compared to financial incentives alone, during and after the intervention. |

経済的インセンティブ群（FI群）は、3か月間の介入を行った。介入前後で、身体活動量とソーシャルキャピタルを評価した。また、身体活動量とソーシャルキャピタルの持続効果に対する各インセンティブの効果は、介入終了6ヶ月後に評価をした。FI群は介入の間、歩数によってひと月当たり500円～700円の範囲で支払いを受けた。 |
The financial incentive group (FI group) underwent a three-month intervention. Measurements of physical activity and social capital was performed before and after the intervention. Additionally, the effects of incentives on physical activity and social capital maintenance was measured six months post-intervention. FI group received a payment ranging from US$4.40 to US$6.20 per month depending on the number of steps taken during the intervention. |

ソーシャルネットワークインセンティブ＋経済的インセンティブ群（SNI+FI群）は、3か月間の介入を行った。介入前後で、身体活動量とソーシャルキャピタルを評価した。また、身体活動量とソーシャルキャピタルの持続効果に対する各インセンティブの効果は、介入終了6ヶ月後に評価をした。FI群は介入の間、歩数によってひと月当たり500円～700円の範囲で支払いを受けた。もう一方の群は、この経済的インセンティブに加えてソーシャルネットワークインセンティブを与えた。SNI+FI群はピアプレッシャーの力を利用するために3人で歩く。対象者には、1週間に1回3人で歩くように伝えた。更に、経済的インセンティブは仲間の中で最も多い歩数が反映された。 |
The social network incentive plus financial incentive group (SNI+FI group) underwent a three-month intervention. Measurements of physical activity and social capital was performed before and after the intervention. Additionally, the effects of incentives on physical activity and social capital maintenance was measured six months post-intervention. In SNI+FI group, we provided a social network incentive in addition to the financial incentive (US$4.40-US$6.20 per month). The SNI+FI group walked in three people to use the power of peer pressure. The participants was informed that they would walk in groups of three people about once a week. Furthermore, their rewards was designed to reflect the largest number of steps taken among buddies. |

| 主な結果/Results |
身体活動量において、両群間で交互作用が認めれた。SNI+FI群は、介入前に比べて介入終了6ヶ月後において身体活動量の有意な増加が認められた。しかしながら、FI群においては、観察期間中に有意な差は認められなかった。ソーシャルキャピタルにおいては、信頼に交互作用の傾向がみられた。SNI+FI群において、介入前と比べて介入後と介入終了６ヶ月後に増加傾向が認められた。 |
There was a statistically significant interaction between group and time. The SNI+FI group increased significantly between the pre-intervention and the six-month post-intervention periods. However, the FI group showed no statistically significant improvement in physical activity during the observation period. In social capital, trust was close to significance. The SNI+FI group increased close to significantly between the pre-intervention and the three month, and the six-month post-intervention periods. |

| 参加者の流れ/Participant flow |
本研究の参加者は、日本の熊本で、いくつかの異なった地域にリーフレットを配布し募集された。2017年8月から9月まで、44名の65歳以上の高齢女性が募集された。研究開始前に、対象者はFI群とSNI+FI群にランダムに分けられた。グループ分けは、参加者に機密にした。介入中、FI群では2名、SNI+FI群では3名がドロップアウトした。最終的に、FI群が21名、SNI+FI群が18名で構成された。 |
A participants of this study were recruited by handing out leaflets in several different regions in Kumamoto, Japan. Forty-four elderly women over 65 years of age were recruited between August 2017 and September 2017. Before starting the study, the participants were divided randomly into a financial incentive group (FI group) and an FI plus social network incentive group (SNI+FI group). The grouping methods was confidential to the participants. During the intervention, two participants in the FI group and three in the SNI+FI group dropped out. Eventually, the study groups comprised 21 participants in the FI group and 18 participants in the SNI+FI group. |
