The conceptual model is arranged from left to right in a single horizontal flow with an additional lower pathway. On the left side, two rectangular boxes appear: the upper box is labeled “Social Networking Sites Addiction (S N S A)” and the lower box is labeled “Digital Stress (D S)”. In the center, a rectangular box labeled “Psychological Strain” is placed. To its right, another rectangular box labeled “Work Performance” appears. On the far right, a rectangular box labeled “Life Satisfaction” is shown. An arrow from “Social Networking Sites Addiction (S N S A)” leads to “Psychological Strain” and is labeled “H 1 a”. Above this arrow, the coefficients read “Ger: 0.37 three asterisk” and “Jap: 0.24 three asterisk”. An arrow from “Digital Stress (D S)” leads to “Psychological Strain” and is labeled “H 1 b”. Below this arrow, the coefficients read “Ger: 0.26 three asterisk” and “Jap: 0.14 asterisk”. An arrow from “Psychological Strain” leads to “Work Performance” and is labeled “H 2 a”. Above this arrow, the coefficients are marked in bold and read “Ger: minus 0.34 three asterisk” and “Jap: minus 0.42 three asterisk”. A second pathway from “Psychological Strain” extends downward and then horizontally to “Life Satisfaction” and is labeled “H 2 b”. Along this lower path, the coefficients read “Ger: minus 0.38 three asterisk” and “Jap: minus 0.34 three asterisk”. An arrow from “Work Performance” leads to “Life Satisfaction” and is labeled “H 3”. Above this arrow, the coefficients read “Ger: 0.15 double asterisk” and “Jap: 0.16 asterisk”. Near the “Life Satisfaction” box, two values are displayed: “R-squared subscript Ger equals 0.20” and “R-squared subscript Jap equals 0.18”.Conceptual model and results.
